Write Operation
Write operation, defined as data going from the micro-controller to the ADNS-2080, 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
write sequence. The second byte contains the data. The ADNS-2080 reads SDIO on rising edges of SCLK
