7.4.3 Register Power Down Mode
The mouse sensor can be placed in a power-down mode by setting 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 bit 3 in the configuration register via a serial port write operation. In power-down mode,
the serial interface watchdog timer is not available. But, The serial interface still can read/write normally. For an
accurate report after leave power down mode, wait about 3ms before the micro-controller is able to issue any
write/read operation to the mouse sensor.

7.5 Error Detection
1. The micro-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 product ID
register
