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. Agilent 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. If the
motion register has not been read for long time, at 400 cpi it may take up to 16 read cycles to clear the buffers, at 1600 cpi, up to 64 cycles.
Alternatively, writing to the Motion_Clear register (register 0x12) will clear all stored motion at once.
Delta_X
Address: 0x03
