triggering the write. When PROV is set high, the current receive data byte is
processed as part of the channel as indicated by CHAN[9:0]. When PROV is
set low, the current time-slot does not belong to any channel and the receive
data byte ignored. PROV reflects the value written until the completion of a
subsequent indirect read operation.
CDLBEN:
The indirect channel based diagnostic loopback enable bit (CDLBEN) reports
the loopback enable flag read from channel provision RAM after an indirect
read operation has complete. The loopback enable flag to be written to the
channel provision RAM, in an indirect write operation, must be set up in this
register before triggering the write. When CDLBEN is set high, the current
receive data byte is to be over-written by data retrieved from the loopback
FIFO of the channel as indicated by CHAN[9:0]. When CDLBEN is set low,
the current receive data byte is processed normally. CDLBEN reflects the
value written until the completion of a subsequent indirect read operation.
