Notes for Motion:
1. Reading this register freezes the Delta_X and Delta_Y register values. Read this register before reading the Delta_X and Delta_Y registers. If
Delta_X and Delta_Y are not read before the motion register is read a second time, the data in Delta_X and Delta_Y will be lost.
2. Avago Technologies RECOMMENDS that registers 0x02, 0x03 and 0x04 be read sequentially. See Motion burst mode also.
3. Internal buffers can accumulate more than eight bits of motion for X or Y. If either one of the internal buffers overflows, then absolute path data
is lost and the OVF bit is set. This bit is cleared once some motion has been read from the Delta_X and Delta_Y registers, and if the buffers are
not at full scale. Since more data is present in the buffers, the cycle of reading the Motion, Delta_X and Delta_Y registers should be repeated
until the motion bit (MOT) is cleared. Until MOT is cleared, either the Delta_X or Delta_Y registers will read either positive or negative full scale.
Delta_X
Address: 0x03
Access: Read
Reset Value: 0x00
Data Type: Eight bit 2’s complement number.
USAGE: X movement is counts since last report. Absolute value is determined by resolution. Reading clears the
register.
