MSTPCR is a 16-bit readable/writable register that performs module stop mode control.
When the MSTP10 bit or MSTP4 bit in MSTPCR is set to 1, D/A 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 19.5, 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 10—Module Stop (MSTP10): Specifies the D/A converter channel 0 and 1module stop mode.
