Description

DEOP0

Completion output for DMA external transfer. This function is enabled when the

external transfer end output for DMA is enabled.

DSTP0

C

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.

DREQ1

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-

C tentionally turned on.

PB3

General purpose input/output port.

DACK1

PB4

External acknowledge output for DMA transfer requests. This function is enabled

when the transfer request acceptance output for DMA is enabled.

C

General purpose input/output port. This function is enabled when the external

transfer request acceptance output for DMA is disabled.

DEOP1

Completion output for DMA external transfer. This function is enabled when the

external transfer end output for DMA is enabled.

DSTP1

C

Stop input for DMA external transfer. This function is enabled when the external

transfer stop input for DMA is enabled.

PB5

DMA fly-by transfer write strobe output is enabled.

C

General purpose input/output port. This function is enabled when the DMA fly-by

transfer write strobe output is disabled.

IORD

PB7

Read storobe output for DMA fly-by transfer. This function is enabled when the
