Conversion time of the built-in A/D converter using the successive comparison method is 280s. The necessary pin can be programmed to A/D analog input in 1 bit units, and P2-3 can be set to the reference voltage input. Internal power supply (VDD) or constant voltage (VEE) can be used as the reference voltage. In addition, constant voltage (VEE) can be input to the A/D analog input so battery voltage, etc., can be easily detected. The reference voltage input, for which a built-in operational amp is used, has high impedance. The A/D converter, and their control are all executed by program. I/O port 3; /Buzzer output; P3-0 45~46 P3-1/ BUZR 2 bits I/O ports, whose input/output can be programmed in 1 bit units. The P3-1 pin also functions as the output for the built-in buzzer circuit.

(Continued) Pin No. Symbol HOLD mode control input; Input pin for request/release HOLD mode. Normally, this pin is used to input radio mode selection signals or battery detection signals. HOLD mode includes CLOCK STOP mode (stops crystal oscillation) and WAIT mode (halts CPU). Setting is implemented with the CKSTP instruction or the WAIT instruction. When the CKSTP instruction is executed, request/release of the HOLD mode depends on the internal MODE bit. If the MODE bit is " (MODE-0), executing 0" 49
HOLD
Description
the CKSTP instruction while the HOLD pin is at low level stops the clock generator and the CPU and changes to memory back-up mode. If the MODE bit is " (MODE1" 1), executing the CKSTP instruction enters memory back-up mode regardless of the level of the HOLD pin. Memory back-up is release when the HOLD pin goes high in MODE-0, or when the level of the HOLD pin low in MODE-1. When memory back-up mode is entered by executing a WAIT instruction, any change in the HOLD pin input releases the mode. In memory back-up mode, current consumption is low (below 10A), and all the output pins (e.g., display output, output ports) are automatically set to low level. TEST mode control input; Input pin used for controlling TEST mode. High level indicates TEST mode, while low level indicates normal operation. The pin is normally used at low level or noconnection (NC). (A pull-down resistor is built-in). IF signal input/Input port; IF counter' IF signal input for counting the IF signals of the FM and AM bands and s detecting the automatic stop position. The input frequency is between 0.35~12MHz (0.2VP-P(Min)). A built-in input amp

and C coupling allow operation at low-level input. The IF counter is a 20 bit counter with optional gate times of 1, 4, 16, and 64ms. 20 bit of data can be readily stored in memory. This input pin can be programmed for use as an input port (IN port). CMOS input is used when the pin is set as an IN port. Phase comparison output /Output port; Phase comparison output; PLL' phase comparison tri-state output pins. s When the programmable counter' prescaler output is higher than the reference s frequency, output is at high level. When output is lower than the reference frequency, high impedance output is obtained. Because DO1 and DO2 are output in parallel, optimal filter constants can be designed for the FM/VHF and AM bands. Pin DO1 can be programmed to high impedance or programmed as an output port (OT). Thus the pins can be used to improve lock-up time or used as output ports. (To be continued)

(Continued) Pin No. Symbol Power-supply pins; Pins to which power is applied. Normally, VDD=1.8~3.6V (3.0V Typ.) is applied. 56 VDD In back-up mode (when CKSTP instructions are being executed), voltage can be lowered to 1.0V. If voltage falls below 1.5V while the CPU is operating, the CPU stops to prevent malfunction (STOP mode). When the voltage rises above 1.5V, the CPU restarts. STOP mode can be detected by checking the STOP F/F bit. If necessary, execute initialization or adjust clock by program. When detecting or preventing CPU malfunctions using an external circuit, STOP 53 GND mode can be invalidated and rendered non-operative by program. In that case, all four bits of the internal TEST port should be set to " . 1" If more than 1.8V is applied when the pin voltage is 0, the device' system is reset s and the program starts from address " . (power on reset).(Note) 0" To operate the power on reset, the power supply should start up in 10~100ms. FM programmable counter input; Programmable counter input pin for FM,VHF band. The 1/2+pulse swallow system (VHF mode) and the pulse swallow system (FM 54 FMIN mode) are selectable freely by program. At the VHF mode, local oscillation output (VCO output) of 50~230MHz (0.2VP-P(Min)) is input and FM mode, 40~130MHz (0.2VP-P (Min)) is input. A built-in input amp and C coupling allow operation at lowlevel input. (Note) when in the PLL OFF mode or when set to AMIN input, the input is pulled down. AM local oscillator signal input; Programmable counter input pin for AM band. The pulse swallow system (HF mode) and direct dividing system (LF mode) are freely 55 AMIN selectable by program. At the HF mode, local oscillation output (VCO output) of 1~45MHz (0.2VP-P(Min)) is input and LF mode, 0.5~12MHz (0.2VP-P(Min)) is input. Built-in input amp operates with low-level input using a C coupling. (Note) When in PLL OFF mode or when set to FMIN input, the input is pulled down. Reset input; Input pin for system reset signals.
