DREQ1: DMA external transfer request input. When selected as a DMA
startup source, this input is in use at all times, so that output from other
functions must be stopped unless used intentionally.
PB3: General purpose input/output port.
DACK1: DMA external transfer request acknowledge output. This
function is valid when the DMA transfer request acknowledge output
setting is enabled.
PB4: General purpose input/output port. This function is enabled when
the DNA transfer request acknowledge output setting is disabled.
DEOP1: DMA external transfer end output. This function is valid when
the DMA external transfer end output setting is enabled.
DSTP1: DMA external transfer stop input. This function is valid when the
DMA external transfer stop input setting is enabled.
PB5: General purpose input/output port. This function is valid when the
DMA external transfer end output selection and the DMA external
transfer stop input selection are disabled.

Clock (oscillator) input
IOWR: Write strobe output for DMA fly-by transfer. This function is valid
when the DMA fly-by transfer write strobe output setting is enabled.
PB6: General purpose input/output port. This function is valid when the
DMA fly-by transfer write strobe output setting is disabled.
IORD: Read strobe output for DMA fly-by transfer. This function is valid
when the DMA fly-by transfer read strobe output setting is enabled.
PB7: General purpose input/output port. This function is valid when the
DMA fly-by transfer read strobe output setting is disabled.
CS0: Chip select output. This function is valid when the chip select 0
output setting is enabled.
PA1: General purpose input/output port. This function is valid when the
chip select 0 output setting is disabled.
CS1: Chip select output. This function is valid when the chip select 1
output setting is enabled.
PA1: General purpose input/output port. This function is valid when the
chip select 1 output setting is disabled.
CS2: Chip select output. This function is valid when the chip select 2
output setting is enabled.
PA2: General purpose input/output port. This function is valid when the
chip select 2 output setting is disabled.
CS3: Chip select output. This function is valid when the chip select 3
output setting is enabled.
PA3: General purpose input/output port. This function is valid when the
chip select 3 output setting is disabled.
