4. Function Description
4.1 Agilent Serial Interface and Control Register
Synchronous Serial Port The synchronous serial port is used to set and read parameters in Agilent sensor IC, and can be used to read out the motion information. The EKM8003 always initiates communication. SCLK: The serial port clock. It is always generate by EKM8003. SDIO: The serial data line. PD: Power Down line is used to force re-synchronization between the EKM8003 and the ADNS-2051 in case of an error. It also can be used to place the ADNS-2051 in low power mode to meet some special case.
Write Operation Write operations, where data is going from the EKM8003 to Agilent sensor IC, is always initiated by the micro-controller and consists of two bytes. The first byte contains the address (seven bits) and has a"1" as its MSB to indicate data direction. The second byte contains the data. The transfer is synchronized by SCLK. The EKM8003 changes SDIO on falling edges of SCLK.
Read Operation A read operation, which means that data is going from Agilent sensor IC to the EKM8003, is always initiated by the EKM8003 and consists of two bytes. The first byte contains the address, is written by the EKM8003, and has a "0" as its MSB to indicate data direction. The second byte contains the data and is driven by Agilent sensor IC. The transfer is synchronized by SCLK. SDIO is changed on falling edges of SCLK and read on every rising edge of SCLK. The EKM8003 will go to a high Z state after the last address data bit. During a read operation, SCLK will delay after the last address data bit to ensure that Agilent sensor IC has at least 100us to prepare the requested data.
Error Detection and Recovery of ADNS-2051 The EKM8003 will verify the synchronization of the serial port by periodically reading the product ID register of ADSN-2051. Once the EKM8003 and the ADNS-2051 get out of sync, then the EKM8003 will output a valid PD plus to resync.
Error Detection and Recovery of ADNS-2610/2620 1. The ADNS-2610/2620 and the microcontroller might get out of synchronization due to ESD events, power supply droops or microcontroller firmware flaws. The ADNS-2610/2620 has a transaction timer for the serial port. If the sixteenth SCK rising edge is spaced more than approximately 90 milliseconds from the first SCK edge of the current transaction, the serial port will reset. Invalid addresses: - Writing to an invalid address will have no effect. Reading from an invalid address will return all zeros.

4.
Collision detection on SDIO - The only time that the ADNS-2610/2620 drives the SDIO line is during a READ operation. To avoid data collisions, the microcontroller should relinquish SDIO before the falling edge of SCK after the last address bit. Then the ADNS-2610/2620 begins to drive SDIO after the next rising edge of SCK. Next, the ADNS-2610/2620 relinquishes SDIO within 160 ns of the falling SCK edge after the last data bit. The microcontroller can begin driving SDIO any time after that. In order to maintain low power consumption in normal operation or when the PD pin is pulled high, the microcontroller should not leave SDIO floating until the next transmission (although that will not cause any communication difficulties). In case of synchronization failure, both the ADNS-2610/2620 and the microcontroller may drive SDIO. The ADNS-2610/2620 can withstand 30 mA of short circuit current and will withstand infinite duration short circuit conditions. The microcontroller can verify a successful write operation by issuing a read command to the same address and comparing the written data to the read data. The microcontroller can verify the synchronization of the serial port by periodically reading the product ID from status register.

Optical sensor resolution selection
Optical Sensor ANDS-2051 resolution can be programmed as 400 or 800 cpi (counts per inch). The EKM8003 has a selection pin, CPIS, to select the resolution. The default resolution is 400 cpi. If the selection pin is tied to ground, the EKM8003 will program the ANDS-2051 to 800 cpi. To program the resolution, the EKM8003 write data into the ANDS-2051's configuration register address, 0x0a.

Registers of ADNS-2051
Product ID Address:0x00 Reset Value: 0x02 Usage: The value in this register does not change, it can be used to verify that the serial communications link is OK.

If so, then the EKM8003 should read registers 0x03 and 0x04 to get the accumulated motion. It also tells if the motion buffers have overflowed and whether or not an LED fault occurred since the last reading. The current resolution is also shown.
