8.2.9
MSTPCRA is an 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 sections 21A.5, 21B.5, Module Stop Mode.
MSTPCRA is initialized to H'3F by a reset and in hardware standby mode. It is not initialized in
software standby mode.
Bit 6—Module Stop (MSTPA6): Specifies the DTC module stop mode.

8.3.1
When activated, the DTC reads register information that is already stored in memory and transfers
data on the basis of that register information. After the data transfer, it writes updated register
information back to memory. Pre-storage of register information in memory makes it possible to
transfer data over any required number of channels. Setting the CHNE bit to 1 makes it possible to
perform a number of transfers with a single activation.
