16.11.2 Register Descriptions
The CRC operation circuit has the following registers.
• CRC control register (CRCCR)
• CRC data input register (CRCDIR)
• CRC data output register (CRCDOR)
(1)
CRCCR initializes the CRC operation circuit, switches the operation mode, and selects the
generating polynomial.

The initial value should not be changed.
CRC Operation Switch
Selects CRC code generation for LSB-first or MSB-first
Communication.
0: Performs CRC operation for LSB-first
1: Performs CRC operation for MSB-first

Communication. The lower byte (bits 7 to 0) is first
transmitted when CRCDOR contents (CRC code)
are divided into two bytes to be transmitted in two
parts.
Communication. The upper byte (bits 15 to 8) is first
transmitted when CRCDOR contents (CRC code)
are divided into two bytes to be transmitted in two
parts.
