DMATCR controls enabling or disabling of output from the DMAC transfer end pin. A port can
be set for output automatically, and a transfer end signal output, by setting the appropriate bit. The
TEND pin is available only for channel B in short address mode. Except for the block transfer
mode, a transfer end signal asserts in the transfer cycle in which the transfer counter contents
reaches 0 regardless of the activation source. In the block transfer mode, a transfer end signal
asserts in the transfer cycle in which the block counter contents reaches 0.
