The TEND pins are assigned only to channel B in short address mode.
The transfer end signal indicates the transfer cycle in which the transfer counter reached 0,
regardless of the transfer source. An exception is block transfer mode, in which the transfer end
signal indicates the transfer cycle in which the block counter reached 0.
Bits 3 to 0—Reserved: These bits are always read as 0 and cannot be modified.

MSTPCRA is a 8-bit readable/writable register that performs module stop mode control.
When the MSTPA7 bit in MSTPCR is set to 1, the DMAC 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 reset and in hardware standby mode. It is not initialized by a
manual reset and in software standby mode.
Bit 7—Module Stop (MSTP7): Specifies the DMAC module stop mode.
