MSTPMR is a 32-bit readable register that indicates whether the PCIC/display unit
(DU)/DMAC/GDTA modules are in the module standby state. MSTPMR can be accessed only in
longword.
This register is initialized by a power-on reset by the PRESET pin, power-on reset by WDT
overflow, or H-UDI reset.

Description
Reserved
These bits are always read as 0. The write value
should always be 0.
Module Stop Display Bit PCIC
Indicates the state of clock supply to the PCIC module
When a high level signal is input to the MODE12 pin,
the clock supply to the PCIC is stopped
0: PCIC operates (MODE12 pin: Low level)
1: PCIC stopped (MODE12 pin: High level)
Module Stop Display Bit DU
Indicates the state of clock supply to the DU module.
When a low level signal is input to the MODE12 or
MODE11 pin, the clock supply to the DU is stopped.
0: DU operates (MODE[12:11] pin: All High level)
1: DU stopped (MODE[12:11] pin: Not all High level)
Reserved
These bits are always read as 0. The write value
should always be 0.
