7.2
Table 7.1 shows the pin configuration of the DMAC.
The corresponding port to the DACK pin automatically enters the output state by the setting of the
single address transfer mode. When the DREQ pin is used, the corresponding port must not enter
the output state. Whether the corresponding port to the TEND/DRAK pin is used as TEND/DRAK
pin can be set by the register.
