14.11.4 Note on CRC Operation Circuit
Note that the sequence to transmit the CRC code differs between LSB-first transmission and
MSB-first transmission.
1. CRC code generation
2. Transmission data
After specifying the operation method, write data to CRCDIR in the sequence of (1) → (2) → (3) → (4).
(i) LSB-first transmission
(ii) MSB-first transmission
Output
CRCDIR
