Bit Field Value Description
31-4 Reserved 0 Reads return to zeros and writes have no effect.
3-0 MKEY3 Mode Key to select operation for Checker CPU Inactivity Monitor
Read in User and Privileged mode. Write in Privileged mode only.
0 Read: Returns current value of the MKEY3.
Write: Active Compare Lockstep mode
6h Read: Returns current value of the MKEY3.
Write: Self-test mode.
