DREQ2: 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.
PG0: General purpose input/output port.
DACK2: DMA external transfer request acknowledge output. This
function is valid when the DMA transfer request acknowledge output
setting is enabled.
PG1: General purpose input/output port. This function is valid when the
DMA transfer request acknowledge output setting is enabled.
DEOP2: DMA external transfer end output. This function is valid when
the DMA external transfer end output setting is enabled.
DSTP2: DMA external transfer stop input. This function is valid when the
DMA external transfer stop input setting is enabled.
PG2: 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.
Mode pins 2-0. The setting of these two pins determines the basic
operating mode. They should be connected to V
