different MDMA stream is granted, or whenever every MDMA stream is
idle. It then counts down to 0 with each MDMA transfer. When this
count decrements from 1 to 0, the next available MDMA stream is
selected.
The
DAB_TRAFFIC_COUNT
the DAB traffic period. It initializes to
is written, or whenever the DAB bus changes direction or
DMA_TC_PER
becomes idle. It then counts down from
system clock (except for DMA stalls). While this count is nonzero, same
direction DAB accesses are treated preferentially. When this count decre-
ments from 1 to 0, the opposite direction DAB access is treated
preferentially, which may result in a direction change. When this count is
0 and a DAB bus access occurs, the count is reloaded from
DAB_TRAFFIC_PERIOD
The
DEB_TRAFFIC_COUNT
the DEB traffic period. It initializes to
is written or whenever the DEB bus changes direction or
DMA_TC_PER
becomes idle. It then counts down from
system clock (except for DMA stalls). While this count is nonzero, same
direction DEB accesses are treated preferentially. When this count decre-
ments from 1 to 0, the opposite direction DEB access is treated
preferentially, which may result in a direction change. When this count is
0 and a DEB bus access occurs, the count is reloaded from
DEB_TRAFFIC_PERIOD
The
DCB_TRAFFIC_COUNT
the DCB traffic period. It initializes to
