SA8E
Transmit Spare Bit (Frame 15, CRC-Multiframe)
First bit in the service word of frame 15 for international use. Only
significant in CRC-multiframe format. If not used, this bit should be
fixed to ‘1’. The information of XSP.XS15 will be shifted into internal
transmission buffer with beginning of the next following transmitted
CRC multiframe.
If automatic transmission of submultiframe status is enabled via bit
XSP.AXS, or, if one of the time-slot 0 transparent modes XSP.TT0 or
TSWM.TSIF is enabled, bit XSP.XS15 will be ignored.
SA Bit Signaling Enable

Initial value loaded into the transmit bit counter at the trigger edge of
SCLKX when the synchronous pulse at port SYPX / XMFS is active
Refer to register XC1.
SA7E
H
Standard operation.
Setting this bit it will be possible to send / receive a LAPD
protocol in any combination of the SA8- SA4 bit positions in the
outgoing / incoming data stream. The on chip signaling
controller has to be configured in the HDLC/LAPD mode. In
transmit direction together with these bits the TSWM.TSA8-4
bits must be set to enable transmission to the remote end
transparently through the FALC.
