MSTPCR is a 8-bit readable/writable register that performs module stop mode control.
When the MSTPA1 bit in MSTPCR is set to 1, A/D converter operation stops at the end of the bus
cycle and a transition is made to module stop mode. Registers cannot be read or written to in
module stop mode. For details, see section 22.5, Module Stop Mode.
MSTPCRA is initialized to H'3F by a reset and in hardware standby mode. It is not initialized by a
reset and in software standby mode.
