MSTPCRA and MSTPCRC are an 8-bit readable/writable registers that performs module stop
mode control. When the MSTPA2 and MSTPC5 are set to 1, the D/A converter halts and enters
module stop mode at the end of the bus cycle. Register read/write is disenabled in module stop
mode. See section 24.5, Module Stop Mode, for details.
MSTPCRA is initialized to H'3F by a power-on reset and in hardware standby mode. MSTPCRC
is initialized to H'FF by a power-on reset and in hardware standby mode. It is not initialized by a
manual reset and in software standby mode.
