Default
Bit 0/Receive SS7 Fill In Signal Unit Delete (RSFD).
Bit 1/Unused, must be set to zero for proper operation.
Bit 2/Unused, must be set to zero for proper operation.
Bit 3/HDLC Disable. (HDLCD) Setting this bit will disable the transmit and receive HDLC function.
Bit 4/Unused, must be set to zero for proper operation.
Bit 5/Unused, must be set to zero for proper operation.
Bit 6/Receive HDLC Mapping Select (RHMS).
Bit 7/Receive HDLC Reset (RHR). Will reset the receive HDLC controller and flush the receive FIFO. Must be cleared and
set again for a subsequent reset.
0 = normal operation. All FISUs are stored in the receive FIFO and reported to the host.
1 = When a consecutive FISU having the same BSN the previous FISU is detected, it is deleted without host
intervention.
0 = transmit and receive HDLC enabled
1 = transmit and receive HDLC disabled
0 = receive HDLC assigned to channels
1 = receive HDLC assigned to FDL (T1 mode), Sa Bits (E1 mode)
0 = normal operation
1 = reset receive HDLC controller and flush the receive FIFO
