14.11.2 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.
