(4) SPI CRC Register (SPICR)
(a) CRCD15:0
The SPICR register contains the CRC calculation result for transmit/receive data.
CRC comparison should be fully considered when performing Sequential-mode transmit and receive
operation using the FIFOs.
CRCRX_TX_B and CRCRESET_B bits in the SPICT register are loaded into this
register. When using the CRC16 algorithm, all the bits participate in the CRC
generation. When using the CRC7 algorithm, only the lower seven bits participates in
the CRC generation. The following describes the steps required to calculate the CRC16
for the transmit data.

The CRC result which is calculated according to the settings of the CRC16_7_b,
First, initialize the CRC calculation register by writing a 1 to the CRCRESET_B bit
Then, by writing the transmit data into the SPITD register, complete the
The SPIST<TEND> bit should be checked to confirm whether the reception is
