8.3.1.7 Debug Mode Transition Status Register (ME_DMTS)
This register provides the status of different factors which influence mode transitions. It is used to give an
indication of why a mode transition indicated by ME_GS.S_MTRANS may be taking longer than
expected.
NOTE
The ME_DMTS register does not indicate whether a mode transition is
ongoing. Therefore, some ME_DMTS bits may still be asserted after the
mode transition has completed.

Table 8-10. Debug Mode Transition Status Register (ME_DMTS) Field Descriptions
Field Description
MPH_BUSY MC_ME/MC_PCU Handshake Busy indicator — This bit is set if the MC_ME has requested a mode
change from the MC_PCU and the MC_PCU has not yet responded. It is cleared when the MC_PCU
has responded.
0 Handshake is not busy
1 Handshake is busy
PMC_PROG MC_PCU Mode Change in Progress indicator — This bit is set if the MC_PCU is in the process of
powering up or down power domains. It is cleared when all power-up/down processes have
completed.
0 Power-up/down transition is not in progress
1 Power-up/down transition is in progress
