CHAN[4:0]:

The indirect data bits (CHAN[4:0]) report the channel number read from the

channel provision RAM after an indirect read operation has completed.

Channel number to be written to the channel provision RAM in an indirect

write operation must be set up in this register before triggering the write.

CHAN[4:0] reflects the value written until the completion of a subsequent

indirect read operation.

PROV:

The indirect provision enable bit (PROV) reports the channel provision enable

flag read from the channel provision RAM after an indirect read operation has

completed. The provision 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 PROV is set high, the current receive data byte is

processed as part of the channel as indicated by CHAN[4:0]. 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

receive data byte is to be over-written by data retrieved from the loopback

FIFO of the channel as indicated by CHAN[4:0]. 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.
