... Synchronous Serial Port The synchronous serial port is used to set and read pa- rameters in the ADNS-2030, and can be used to read out the motion information instead of the quadrature data pins. The port is a two wire, half duplex port. The host micro- controller always initiates communication; the ADNS- 2030 never initiates data transfers ...

... SCLK is driven by the microcontroller. 1 The micro-controller must high Z state after the last address data bit. The ADNS-2030 will go to the high Z state after the last data bit. (see detail “B” in Figure 29). One other thing to note during a read operation is that SCLK will need to be delayed after the last address data bit to ensure that the ADNS-2030 has at least 100 µ ...

... There are times when the SDIO line from the ADNS-2030 should be in the Hi-Z state. If the microprocessor has com- pleted a write to the ADNS-2030, the SDIO line is Hi-Z, since the SDIO pin is still configured as an input. However, if the last operation from the microprocessor was a read, the ADNS-2030 will hold the D0 state on SDIO until a falling edge of SCLK ...

... This assumes that the mi- croprocessor and the ADNS-2030 share the same power supply. If not, then the microprocessor must wait t from ADNS-2030 V valid. Then when the SCLK toggles DD for the address, the ADNS-2030 will be in sync with the microprocessor >t SPTT ...
