The FALC56 supports the DL-channel protocol using the ESF or F72 (SLC96) format as
follows (HDLC channel 1 only):
• Sampling of DL-bits is done on a multiframe basis and stored in the registers
• If enabled via CCR1.EDLX/EITS = 10, the DL-bit information is stored in the receive
Data Sheet
RDL(3:1). A receive multiframe begin interrupt is provided to read the received data
DL-bits. The contents of registers XDL(3:1) is subsequently sent out on the transmit
multiframe basis if it is enabled via FMR1.EDL. A transmit multiframe begin interrupt
requests for writing new information to the DL-bit registers.
FIFO of the signaling controller. The DL-bits stored in the XFIFO are inserted into the
outgoing data stream. If CCR1.EDLX is cleared, a HDLC frame or a transparent frame
can be sent or received via the RFIFO/XFIFO.
