Mode Entry Module (MC_ME)
Software can monitor the mode transition status by reading the S_MTRANS bit of the register. The mode
transition latency can differ from one mode to another depending on the resources’ availability before the
new mode request and the target mode’s requirements.
If a mode transition is taking longer to complete than is expected, the ME_DMTS register can indicate
which process is still in progress.
