DMA Terminal Control Register (DMATCR)

Bit : 7

DMATCR is an 8-bit readable/writable register that controls enabling or disabling of DMAC transfer end pin output. A
port can be set for output automatically, and a transfer end signal output, by setting the appropriate bit.
DMATCR is initialized to H'00 by a reset, and in standby mode.
Bits 7 and 6—Reserved: These bits cannot be modified and are always read as 0.
Bit 5—Transfer End Enable 1 (TEE1): Enables or disables transfer end pin 1 (TEND1) output.

Bit 4—Transfer End Enable 0 (TEE0): Enables or disables transfer end pin 0 (TEND0) output.

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 cannot be modified and are always read as 0.
