31.3.10.12 Effects of Sleep Mode on CRC

When CRCCTRL.RUNSTDBY = 1 and STATUS.PRM=0 (Flash Auto Standby) the CRC Logic continues operation during Standby mode. Otherwise, CRC logic halts operations. When CRCCTRL.RUNSTDBY = 0 OR STATUS.PRM=1 (Flash Hibernate) the CRC Logic halts operation during Standby mode. Unlike PAUSE, the counters also stop.

Note that the PRM status can change on entry to Standby based on CTRLB.SLP. The CRC logic uses the state of PRM when the device is in Standby to determine if the CRC runs or not.
