MSTPCRB is an 8-bit readable/writable register that perform module stop mode control.
When the MSTPB4 or MSTPB3 bit is set to 1, operation of the corresponding IIC channel is
halted at the end of the bus cycle, and a transition is made to module stop mode. For details, see
section 23A.5, 23B.5, Module Stop Mode.
MSTPCRB is initialized to H'FF by a power-on reset and in hardware standby mode. It is not
initialized in software standby mode.
Bit 4—Module Stop (MSTPB4): Specifies IIC channel 0 module stop mode.
