Module Stop Control Register A (MSTPCRA)

Bit : 7
MSTPA7
Initial value : 0
R/W : R/W
MSTPCRA is a 8-bit readable/writable register that performs module stop mode control.
When the MSTPA6 bit in MSTPCRA is set to 1, the DTC operation stops at the end of the bus
cycle and a transition is made to module stop mode. However, 1 cannot be written in the MSTPA6
bit while the DTC is operating. 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 in manual reset and software standby mode.
Bit 6—Module Stop (MSTPA6): Specifies the DTC module stop mode.
