20.2.2
MSTCR is an 8-bit readable/writable register that controls output of the system clock ( ). It also
controls the module standby function, which places individual on-chip supporting modules in the
standby state. Module standby can be designated for the ITU, SCI0, SCI1, DMAC, refresh
controller, and A/D converter modules.

Read/Write
MSTCR is initialized to H'40 by a reset and in hardware standby mode. It is not initialized in
software standby mode.
Bit 7— Clock Stop (PSTOP): Enables or disables output of the system clock ( ).
Bit 6—Reserved: Read-only bit, always read as 1.
Bit 5—Module Standby 5 (MSTOP5): Selects whether to place the ITU in standby.
