6.5.2 Register Power Down Mode
PAN301A 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 PAN301A.

6.6 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.
