MSTPCR is a 16-bit readable/writable register that performs module stop mode control.
When the MSTP15 bit in MSTPCR is set to 1, the DMAC operation stops at the end of the bus
cycle and a transition is made to module stop mode. For details, see section 21.5, 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 15—Module Stop (MSTP15): Specifies the DMAC module stop mode.
