NOTES: Avago RECOMMENDS that registers 0x03 and 0x04 be read sequentially.
Delta_Y
Access: Read
Data Type: Eight bit 2’s complement number.
USAGE: Y movement is counts since last report. Absolute value is determined by resolution. Reading clears the register.

The maximum SQUAL register value is 167. Since small changes in the current frame can result in changes in
SQUAL, variations in SQUAL when looking at a surface are expected.
