Enable Bit Robbing Marker
A one in this bit will mark the robbed bit positions on the system
highway. RSIGM marks the receive and XSIGM marks the transmit
robbed bits.
Enable pure Multiframe Begin Signals
Only valid if ESF or F72 format is selected.
If set, signals RMFB and XMFB indicate only the multiframe begin.
Additional pulses (every 12 frames) are disabled.
Bit Robbing Force One
Setting this bit forces the robbed bits high transmitted on port RDO.
The received signaling data stream for the signaling controller is not
influenced by this bit.
Initial value loaded into the transmit bit counter at the trigger edge of
SCLKX when the synchronous pulse at port SYPX or XMFS is active
Refer to register XC1.
A write access to this address resets the transmit elastic buffer to its
basic starting position. Therefore, updating the value should only be
done when the QuadFALC is initialized or when the buffer should be
centered. As a consequence a transmit slip may occur.
Initial value loaded into the transmit bit counter at the trigger edge of
SCLKX when the synchronous pulse at port SYPX / XMFS is active
(see figure 55+56).
