Section 16 I
16.2.9
MSTPCR comprises two 8-bit readable/writable registers, and is used to perform module stop
mode control.
When the MSTP4 or MSTP3 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
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.
MSTPCRL Bit 4—Module Stop (MSTP4): Specifies IIC channel 0 module stop mode.
