MSTPCRA is an 8-bit readable/writable register that performs module stop mode control.
When the MSTPA4 and MSTPA0 bits in MSTPCR is set to 1, the 8-bit timer operation stops at
the end of the bus cycle and a transition is made to module stop mode. For details, see section
24.5, Module Stop Mode.
MSTPCRA is initialized to H'3F by a power-on reset and in hardware standby mode. It is not
initialized by a manual reset and in software standby mode.
