MSTPCR is a 16-bit readable/writable register that performs module stop mode control.
When the MSTP9 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 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 9—Module Stop (MSTP9): Specifies the A/D converter module stop mode.
