8-Bit unsigned integer
This register value is made to be the same as ADNS-5020-EN for direct replacement. The alternative PID
is located at Product_ID2 (Address 0x3e). The values in these registers do not change; either one can be
used to verify if the serial communications link is functional.
8-Bit unsigned integer
This register contains the IC revision. It is subject to change when new IC versions are released.
Bit field.
Register 0x02 allows the user to determine if motion has occurred since the last time it was read. If the
MOT bit is set, then the user should read registers 0x03 and 0x04 to get the accumulated motion. Read
this register before reading the Delta_X and Delta_Y registers.
Writing anything to this register clears the MOT bit, Delta_X and Delta_Y registers. The written data
byte is not saved.
