HANDLING DEVICES
1. Be careful never to exceed maximum rated voltages (preventing latch-up)
In CMOS IC devices, a condition known as latch-up may occur if voltages higher than VCC or lower than VSS are applied to input or output pins other than medium-or high-voltage pins, or if the voltage applied between VCC and VSS pins exceeds the rated voltage level. When latch-up occurs, the power supply current increases rapidly causing the possibility of thermal damage to circuit elements. Therefore it is necessary to ensure that maximum ratings are not exceeded in circuit operation. Similarly, when turning the analog power supply on or off, it is necessary to ensure that the analog power supply voltages (AVCC and AVRH) and analog input voltages do not exceed the digital power supply (VCC) .
2. Treatment of unused pins
Leaving unused input pins unconnected can cause abnormal operation or latch-up, leading to permanent damage. Unused input pins should always be pulled up or down through resistance of at least 2 k. Any unused input/output pins may be set to output mode and left open, or set to input mode and treated the same as unused input pins.
3. Treatment of Power Supply Pins (VCC/VSS)
When multiple VCC/VSS pins are present, device design considerations for prevention of latch-up and unwanted electromagnetic interference, abnormal strobe signal operation due to ground level rise, and conformity with total output current ratings require that all power supply pins must be externally connected to power supply or ground. Consideration should be given to connecting power supply sources to the VCC/VSS pins of this device with as low impedance as possible. It is also recommended that a bypass capacitor of approximately 0.1 F be placed between the VCC and VSS lines as close to this device as possible.
4. Crystal Oscillator Circuits
Noise around the X0/X1, or X0A/X1A pins may cause this device to operate abnormally. In the interest of stable operation it is strongly recommended that printed circuit board artwork places ground bypass capacitors as close as possible to the X0/X1, X0A/X1A and crystal oscillator (or ceramic oscillator) and that oscillator lines do not cross the lines of other circuits.
5. Precautions when turning the power supply on
In order to prevent abnormal operation in the chip's internal step-down circuits, a voltage rise time during poweron of 50 s (0.2 V to 2.7 V) or greater should be assured.
6. Supply Voltage Stabilization
Even within the operating range of VCC supply voltage, rapid voltage fluctuations may cause abnormal operation. As a standard for power supply voltage stability, it is recommended that the peak-to-peak VCC ripple voltage at commercial supply frequency (50 MHz to 60 MHz) be 10 % or less of VCC, and that the transient voltage fluctuation be no more than 0.1 V/ms or less when the power supply is turned on or off.
7. Proper power-on/off sequence
The A/D converter power (AVCC, AVRH) and analog input (AN0 to AN7) must be turned on after the digital power supply (VCC) is turned on. The A/D converter power (AVCC, AVRH) and analog input (AN0 to AN7) must be shut off before the digital power supply (VCC) is shut off. Care should be taken that AVRH does not exceed AVCC. Even when pins used as analog input pins are doubled as input ports, be sure that the input voltage does not exceed AVCC. 16
MB90480/485 Series
8. Treatment of power supply pins on models with A/D converters
Even when the A/D converters are not in use, be sure to make the necessary connections AVCC = AVRH = VCC, and AVSS = VSS.
9. Notes on Using Power Supply
Only the MB90485 series usually uses a 3 V power supply. By setting VCC3 = 3 V power supply and VCC5 = 5 V power supply, P20 to P27, P30 to P37, P40 to P47 and P70 to P77 can be interfaced as 5 V power supplies separately from the main 3 V power supply. Note that the analog power supplies (such as AVCC and AVSS) for the A/D converter can be used only as 3 V power supplies.
10. Notes on Using External Clock
Even when using an external clock signal, an oscillation stabilization delay is applied after a power-on reset or when recovering from sub-clock or stop mode. When using an external clock, 25 MHz should be the upper frequency limit. The following figure shows a sample use of external clock signals.
X0
OPEN
X1
11. Treatment of NC pins
NC (internally connected) pins should always be left open.
12. Notes on during operation of PLL clock mode
On this microcontroller, if in case the crystal oscillator breaks off or an external reference clock input stops while the PLL clock mode is selected, a self-oscillator circuit contained in the PLL may continue its operation at its self-running frequency. However, Fujitsu will not guarantee results of operation if such failure occurs.
13. When the MB90480/485 series microcontroller is used as a single system
When the MB90480/485 series microcontroller is used as a single system, use connections so the X0A = VSS, and X1A = Open.
14. Writing to Flash memory
For writing to Flash memory, always ensure that the operating voltage VCC is between 3.0 V and 3.6 V.

*1 : No memory cells from FC0000H to FC7FFFH and FE0000H to FE7FFFH. The upper part of the 00 bank is set up to mirror the image of FF bank ROM, to enable efficient use of small model C compilers. Because the lower 16-bit address of the FF bank and the lower 16-bit address of the 00 bank are the same, enabling reference to tables in ROM without using the for specification in the pointer declaration. For example, in accessing address 00C000H it is actually the contents of ROM at FFC000H that are accessed. If the MS bit in the ROMM register is set to "0", the ROM area in the FF bank will exceed 48 Kbytes and it is not possible to reflect the entire area in the image in the 00 bank. Therefore the image from FF4000H to FFFFFFH is reflected in the 00 bank and the area from FF0000H to FF3FFFH can be seen in the FF bank only. (Continued) 19

Note : If there are two interrupt sources for the same interrupt number, the resource will clear both interrupt request flags at the EI2OS/DMAC interrupt clear signal. Therefore if either of the two sources uses the EI2OS/ DMAC function, the other interrupt function cannot be used. The interrupt request enable bit for the corresponding resource should be set to "0" and interrupt requests from that resource should be handled by software polling.

PERIPHERAL RESOURCES
1. I/O Ports
The I/O ports perform the functions of either sending data from the CPU to the I/O pins, or loading information from the I/O into the CPU, according to the setting of the corresponding port data register (PDR) . The input/ output direction of each I/O pin can be set in individual bit units by the port direction register (DDR) for each I/ O port. The MB90480/485 series has 84 input/output pins. The I/O ports are port 0 through port A.

*1 : The value is set to "" on MB90485 series only. *2 : The initial value of this bit is "XX000000B" on MB90485 series only. * When a set of pins is functioning as a port, the corresponding signal pins are controlled as follows. 0 : Input mode. 1 : Output mode. Reset to "0". Notes : * When any of these registers are accessed using a read-modify-write type instruction (such as a bit set instruction) , the bit specified in the instruction will be set to the indicated value. However, the contents of output registers corresponding to any other bits having input settings will be rewritten to the input values of those pins at that time. For this reason, when changing any pin that has been used for input to output, first write the desired value to the PDR register before setting the DDR register for output. * P76, P77 (MB90485 series only) This port has no DDR. To use P77 and P76 as I2C pins, set the PDR value to "1" so that port data remains enabled (to use P77 and P76 for general purposes, disable I2C) . The port is an open drain output (with no P-ch) . To use it as an input port, therefore, set the PDR to "1" to turn off the output transistor and add a pull-up resistor to the external output. 34

10. 16-bit Reload Timer
The 16-bit reload timer provides a choice of functions, including internal clock signals that count down in synchronization with three types of internal clock, as well as an event count mode that counts down at specified edge detection events in pulse signals input from external pins. This timer defines an underflow as a change in count value from 0000H to FFFFH. Thus an underflow will occur when counting from the value "reload register setting value + 1". The choice of counting operations includes reload mode, in which the count setting values is reloaded and counting continues following an underflow event, and one-shot mode, in which an underflow event causes counting to stop. An interrupt can be generated at counter underflow, and the timer is DTC compatible. (1) Register List * TMCSR (Timer control status register) Timer control status register (high) (TMCSR)

19. Chip Select Function Description
The chip select module generates a chip select signals, which are used to facilitate connections to external memory devices. The MB90480/485 series has four chip select output pins, each having a chip select area register setting that specifies the corresponding hardware area and select signal that is output when access to the corresponding external address is detected. * Chip select function features The chip select function uses two 8-bit registers for each output pin. One of these registers (CARx) is able to detect memory areas in 64 Kbytes units by specifying the upper 8-bit of the address for match detection. The other register (CMRx) can be used to expand the detection area beyond 64 Kbytes by masking bits for match detection. Note that during external bus holds, the CS output is set to high impedance.

23. Address Match Detection Function
When the address is equal to a value set in the address detection register, the instruction code loaded into the CPU is replaced forcibly with the INT9 instruction code (01H). As a result, when the CPU executes a set instruction, the INT9 instruction is executed. Processing by the INT#9 interrupt routine allows the program patching function to be implemented. Two address detection registers are supported. An interrupt enable bit is prepared for each register. If the value set in the address detection register matches an address and if the interrupt enable bit is set at "1", the instruction code loaded into the CPU is replaced forcibly with the INT9 instruction code.

*1 : This parameter is based on VSS = AVSS = 0.0 V. *2 : AVCC and AVRH must not exceed VCC. Also, AVRH must not exceed AVCC. *3 : VI and V0 must not exceed VCC + 0.3 V. However, if the maximum current to/from and input is limited by some means with external components, the ICLAMP rating supersedes the VI rating. *4 : Maximum output current is defined as the peak value for one of the corresponding pins. *5 : Average output current is defined as the average current flow in a 100 ms interval at one of the corresponding pins. *6 : Average total output current is defined as the average current flow in a 100 ms interval at all corresponding pins. *7 : * Applicable to pins : P00 to P07, P10 to P17, P20 to P27, P30 to P37, P40 to P47, P50 to P57, P60 to P67, P70 to P77, P80 to P87, P90 to P97, PA0 to PA3 * Use within recommended operating conditions. * Use at DC voltage (current) . * The +B signal should always be applied with a limiting resistance placed between the +B signal and the microcontroller. * The value of the limiting resistance should be set so that when the +B signal is applied the input current to the microcontroller pin does not exceed rated values, either instantaneously or for prolonged periods. (Continued) 84
MB90480/485 Series
(Continued) * Note that when the microcontroller drive current is low, such as in the power saving modes, the +B input potential may pass through the protective diode and increase the potential at the VCC pin, and this may affect other devices. * Note that if a +B signal is input when the microcontroller power supply is off (not fixed at 0 V) , the power supply is provided from the pins, so that incomplete operation may result. * Note that if the +B input is applied during power-on, the power supply is provided from the pins and the resulting supply voltage may not be sufficient to operate the power-on reset. * Care must be taken not to leave the +B input pin open. * Note that analog system input/output pins other than the A/D input pins (LCD drive pins, comparator input pins, etc.) cannot accept +B signal input. * Sample recommended circuits: * Input/Output Equivalent circuits Protective diode Limiting resistance
