3.10.9.1.1 CRCCR – CRC Control Register

Name: CRCCR
Offset: 0x145
Reset: 0x00

Bit 76543210 
 REFLOREFLICRCRS 
Access RRRRRR/WR/WW 
Reset 00000000 

Bit 7 –  Reserved Bit

This bit is reserved and returns ‘0’ when read.

Bit 6 –  Reserved Bit

This bit is reserved and returns ‘0’ when read.

Bit 5 –  Reserved Bit

This bit is reserved and returns ‘0’ when read.

Bit 4 –  Reserved Bit

This bit is reserved and returns ‘0’ when read.

Bit 3 –  Reserved Bit

This bit is reserved and returns ‘0’ when read.

Bit 2 – REFLO Reflect Data Output Byte

If this parameter is ‘0’, the final value in the CRC register is fed into the output stage directly; otherwise, if this parameter is set to ‘1’, the final register value is reflected first.

Bit 1 – REFLI Reflect Data Input Byte

If this parameter is ‘0’, input bytes are processed with bit 7 being treated as the MSB and bit 0 being treated as the LSB. If it is set to ‘1’, each data input byte is reflected before being processed.

Bit 0 – CRCRS CRC Data Register Reset

This bit is used to reset the CRC data input register and CRC data output register (CRCDIR, CRCDOR). Once written to ‘1’, hardware clears this bit after one clock cycle.
