DMA External input for DMA transfer requests. This
input is used continuously when selected as a DMA
activation trigger. In this case, do not output to this
port unless doing so intentionally.
General purpose input/output port. The pin has this
function when completion output and stop input are
disabled for DMA transfer.
External acknowledge output for DMA transfer
requests. The pin has this function when outputting
DMA transfer request acknowledgement 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 unless doing so intentionally.
General purpose input/output port.
Completion output for DMA external transfer. The
pin has this function when outputting DMA transfer
completion is enabled.
PPG timer output. The pin has this function when
PPG1 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 disabled.
General purpose input/output port. The pin has this
function when outputting a write strobe for DMA
fly-by transfer is disabled.
Clock (oscillation) input.
Clock (oscillation) output.
Mode pins 0 to 2. The levels applied to these pins
set the basic operating mode. Connect V
