8.2.9
MSTPCR is a 16-bit readable/writable register that performs module stop mode control.
When the MSTP14 bit in MSTPCR 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 MSTP14 bit
while the DTC is operating. For details, see section 21.5, 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 14—Module Stop (MSTP14): 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.
Figure 8.2 shows a flowchart of DTC operation.
