calculated CRC value at the end of the transmit data. Figure 3.18.7 below illustrates the
flow chart of the CRC calculation procedures.
(1) Program the SPICT<CRC16_7_B> bit to select the CRC algorithm from CRC7 and
(2) To reset the SPICR register, write a “0” to the CRCRESET_B bit and then write a “1” to
(3) Load the SPITD register with the transmit data, and wait until transmission of all data
(4) Read the SPICR register and obtain the result of the CRC calculation.
(5) Transmit the CRC obtained in step (4) in the same way as step (3).
This section describes how to calculate the CRC16 of the transmit data and to append the
The CRC calculation on the receive data can be performed in the same procedures.
