Section 19 Serial Communication Interface (SCI, IrDA, CRC)
(2)
CRCDIR is an 8-bit readable/writable register, to which the bytes to be CRC-operated are written.
The result is obtained in CRCDOR.
(3)
CRCDOR is a 16-bit readable/writable register that contains the result of CRC operation when the
bytes to be CRC-operated are written to CRCDIR after CRCDOR is cleared. When the CRC
operation result is additionally written to the bytes to which CRC operation is to be performed, the
CRC operation result will be H'0000 if the data contains no CRC error. When bits 1 and 0 in
CRCCR (G1 and G0 bits) are set to 0 and 1, respectively, the lower byte of this register contains
the result.
