7.1.4
Table 7.2 summarizes the DMAC pins.
In short address mode, external request transfer, single address transfer, and transfer end output
are not performed for channel A.
The DMA transfer acknowledge function is used in channel B single address mode in short
address mode.
When the DREQ pin is used, do not designate the corresponding port for output.
With regard to the DACK pins, setting single address transfer automatically sets the corresponding
port to output, functioning as a DACK pin.
With regard to the TEND pins, whether or not the corresponding port is used as a TEND pin can
be specified by means of a register setting.
