31.2.7.12 Effects of Sleep Mode on CRC

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

Note: 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.
