20.2.2
MSTCRH 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 SCI0, SCI1, SCI2.
In modes 1 to 5, MSTCRH is initialized to H'78 by a reset and in hardware standby mode, while
in mode 7 it is initialized to H'F8. It is not initialized in software standby mode.
Bit 7— Clock Stop (PSTOP): Enables or disables output of the system clock ( ).

Bits 6 to 3—Reserved: These bits cannot be modified and are always read as 1.
Bit 2—Module Standby H2 (MSTPH2): Selects whether to place the SCI2 in standby.
