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) output
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.
