PROD_ID
Product ID Register
Access: Read
Data Type: 8-Bit unsigned integer
USAGE: This register contains a unique identification assigned to the ADNS-3000. The value in this register does not
REV_ID
Product ID Register
Access: Read
Data Type: 8-Bit unsigned integer
USAGE: This register contains the IC revision. It is subject to change when new IC versions are released.
MOTION_ST
Motion Status Register
Access: Read/Write
Data Type: Bit field.
USAGE: Register 0x02 allows the user to determine if motion has occurred since the last time it was read. If the MOTION_

change; it can be used to verify that the serial communications link is functional.
ST bit is set, then the user should read registers 0x03 (DELTA_X) and 0x04 (DELTA_Y) to get the accumulated
motion data. Read this register before reading the DELTA_X and DELTA_Y registers. Writing any data into this
register clears MOTION_ST bit, DELTA_X and DELTA_Y registers. However the written data byte will not be
saved.
