Function
External input for DMA transfer requests. This
input is used continuously when external input for
DMA transfer request is enabled. In this case, do
not output to this port unless doing so intentionally.
Refer to "14.3.1 Setting a Transfer Request" for
active level.
General purpose input/output port.
External acknowledge output for DMA transfer
requests. The pin has this function when external
acknowledge output for DMA transfer requests is
enabled.
External trigger input for PPG timer. This input is
used continuously when the corresponding timer
input is enabled. In this case, do not output to this
port and external acknowledge output for DMA
transfer request unless doing so intentionally.
General purpose input/output port.
Completion output for DMA external transfer. The
pin has this function when completion output for
DMA external transfer is enabled.
PPG timer output. The pin has this function when
PPE1 bit is enabled.
General purpose input/output port.
Write strobe output for DMA fly-by transfer. The
pin has this function when outputting a write strobe
for DMA fly-by transfer is enabled.
General purpose input/output port. The pin has
this function when outputting a write strobe for
DMA fly-by transfer is disabled.
Read strobe output for DMA fly-by transfer. The
pin has this function when outputting a read strobe
for DMA fly-by transfer is enabled.
General purpose input/output port. The pin has
this function when outputting a read strobe for
DMA fly-by transfer is disabled.
Clock (oscillation) input.
