31.2.7.13 CRCCTRL – CRC CONTROL REGISTER

RUNSTDBY determines if the CRC will be calculated when in Standby Mode. When RUNSTDBY = 0, the CRC is not calculated. CRC can only be calculated in Standby if STATUS.PRM = 0.

CRCEN is essentially the “enable” and “go” bit. All other CRC related SFR bits and fields must be setup prior to writing CRCEN to one. When CRCEN = 1 all other CRC bits are write protected except CRCEN, CRCRST, and PAUSE.CRCEN auto clears when the operation finishes (CRCDONE==1).

CRCRST resets the CRC SFR bits and returns the FSM to its idle state. The FSM clears CRCRST before returning to idle.
