Section 7 DMA Controller (DMAC)
MAR, IOAR, and ETCR can always be written to regardless of the DMAWER settings. When
modifying these registers, the channel to be modified should be halted.
7.3.7
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.
