MSTPCR, comprising two 8-bit readable/writable registers, performs module stop mode control.
When bit MSTP7, MSTP6, or MSTP5 is set to 1, SCI0, SCI1, or SCI2 operation, respectively,
stops at the end of the bus cycle and a transition is made to module stop mode. For details, see
section 24.5, Module Stop Mode.
MSTPCR is initialized to H'3FFF by a reset and in hardware standby mode. It is not initialized in
software standby mode.
Bit 7—Module Stop (MSTP7): Specifies the SCI0 module stop mode.
