Register 0x110: RCAS Indirect Channel Data and Loop Back Enable
This register contains the data read from the RCAS channel provision RAM after an indirect read
operation or the data to be inserted into the RCAS channel provision RAM in an indirect write
operation.
One channel must be reserved for timeslots that are unprovisioned in an active tributary.
CHAN[9:0]
PROV
The indirect data bits (CHAN[9:0]) report the channel number read from the channel
provision RAM after an indirect read operation has completed. Channel number to be written
to the RCAS channel provision RAM in an indirect write operation must be set up in this
register before triggering the write. CHAN[9:0] reflects the value written until the
completion of a subsequent indirect read operation.
The indirect provision enable bit (PROV) reports the channel provision enable flag read from
the RCAS channel provision RAM after an indirect read operation has completed. The
provision enable flag to be written to the RCAS 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[9:0].
When PROV is set low, the current timeslot does not belong to any channel and the received
data byte ignored. PROV reflects the value written until the completion of a subsequent
indirect read operation.
