7.5.2 Register Power Down Mode
The mouse sensor can be placed in a power down mode by setting PD_enh bit (bit 3) in the configuration
register via a serial port write operation. After setting the configuration register, wait at least 1frame times. To
get the chip out of the power down mode, clear PD_enh bit (bit 3) in the configuration register via a serial port
write operation. In the power down mode, the serial interface watchdog timer is not available (see Section 7.2.2).
But, the serial interface still can read/write normally. For an accurate report after leave the power down mode,
wait about 3ms before the mouse controller is able to issue any write/read operation to the mouse sensor.

7.6 Error Detection
1. The mouse controller can verify success of write operations by issuing a read command to the same address
and comparing written data to read data.
2. The micro controller can verify the synchronization of the serial port by periodically reading the Produc_ID
register.
