Product_ID
Address: 0x00
Access: Read
Reset Value: 0x17
Data Type: 8-Bit unsigned integer
USAGE: This register contains a unique identification assigned to the ADNS-3080. The value in
this register does not change; it can be used to verify that the serial communications link is
functional.
Revision_ID
Address: 0x01
Access: Read
Reset Value: 0xNN
Data Type: 8-Bit unsigned integer.
USAGE: This register contains the IC revision. It is subject to change when new IC versions are
released.
NOTE: The downloaded SROM firmware revision is a separate value and is available in the
SROM_ID register.
Motion
Address: 0x02
Access: Read
Reset Value: 0x00
Data Type: Bit field.
USAGE: Register 0x02 allows the user to determine if motion has occurred since the last time it
was read. If so, then the user should read registers 0x03 and 0x04 to get the accumulated
motion. It also tells if the motion buffers have overflowed, and the current resolution setting.
