Description
152
DEOP0
C
Completion output for DMA external transfer. This function is enabled when the
external transfer end output for DMA is enabled.
DSTP0
Stop input for DMA external transfer. This function is enabled when the external
transfer stop input for DMA is enabled.
PB2
General purpose input/output port. This function is enabled when the external
transfer end output and external transfer stop input for DMA are disabled.
153
DREQ1
C
External input for DMA transfer requests. Since this input is used as required
when selected as a DMA start source, the port output must remain off unless in-
tentionally turned on.
PB3
General purpose input/output port.
154
DACK1
C
External acknowledge output for DMA transfer requests. This function is enabled
when the transfer request acceptance output for DMA is enabled.
PB4
General purpose input/output port. This function is enabled when the external
transfer request acceptance output for DMA is disabled.
155
DEOP1
C
Completion output for DMA external transfer. This function is enabled when the
external transfer end output for DMA is enabled.
DSTP1
Stop input for DMA external transfer. This function is enabled when the external
transfer stop input for DMA is enabled.
PB5
General purpose input/output port. This function is enabled when the external
transfer end output and external transfer stop input for DMA are disabled.
156
IOWR
C
Write strobe output for DMA fly-by transfer. This function is enabled when the
DMA fly-by transfer write strobe output is enabled.
PB6
General purpose input/output port. This function is enabled when the DMA fly-by
transfer write strobe output is disabled.
157
IORD
C
Read storobe output for DMA fly-by transfer. This function is enabled when the
DMA fly-by transfer read strobe output is enabled.
PB7
General purpose input/output port. This function is enabled when the DMA fly-by
transfer read strobe output is disabled.
158
CS0
C
Chip select 0 output. Enable at external bus mode
PA0
General purpose input/output port. This is enabled at single chip mode.
159
CS1
C
Chip select 1 output. This function is enabled when the chip select 1 output is en-
abled.
PA1
General purpose input/output port. This function is enabled when the chip select
1 output is disabled.
160
CS2
C
Chip select 2 output. This function is enabled when the chip select 2 output is en-
abled.
PA2
General purpose input/output port. This function is enabled when the chip select
2 output is disabled.
