to the current mode.

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
CORE_DBG Processor is in Debug mode indicator — This bit is set while the processor is in debug mode.
0 The processor is not in debug mode
1 The processor is in debug mode
SMR
SAFE mode request from MC_RGM is active indicator — This bit is set if a hardware SAFE mode
request has been triggered. It is cleared when the hardware SAFE mode request has been cleared.
0 A SAFE mode request is not active
1 A SAFE mode request is active
VREG_CSR
C_SC
Main VREG dependent Clock Source State Change during mode transition indicator — This bit is set
when a clock source which depends on the main voltage regulator to be powered-up is requested to
change its power up/down state. It is cleared when the clock source has completed its state change.
0 No state change is taking place
1 A state change is taking place
CSRC_CSR
C_SC
(Other) Clock Source dependent Clock Source State Change during mode transition indicator — This
bit is set when a clock source which depends on another clock source to be powered-up is requested
to change its power up/down state. It is cleared when the clock source has completed its state
change.
0 No state change is taking place
1 A state change is taking place
IRCOSC_SC IRCOSC State Change during mode transition indicator — This bit is set when the 16 MHz internal
RC oscillator is requested to change its power up/down state. It is cleared when the 16 MHz internal
RC oscillator has completed its state change.
0 No state change is taking place
1 A state change is taking place
