Data Sheet
Enable Internal Time Slot 0 to 31 Signaling - HDLC Channel 1
0 =
1 =
Interframe Time Fill - HDLC Channel 1
Determines the idle (= no data to be sent) state of the transmit data
coming from the signaling controller.
0
1
Transmit Multiframe Aligned - HDLC Channel 1
Determines the synchronization between the framer and the
corresponding signaling controller.

Note: During the transmission of the XFIFO content, the SYPX or
Continuous logical 1 is output
Continuous flag sequences are output (01111110 bit patterns)
Internal signaling in time slots 0 to 31 defined by registers
RTR(4:1) or TTR(4:1) is disabled.
Internal signaling in time slots 0 to 31 defined by registers
RTR(4:1) or TTR(4:1) is enabled.
The contents of the XFIFO is transmitted without multiframe
alignment.
The contents of the XFIFO is transmitted multiframe aligned.
If CCR1.EDLXis set, transmission of DL-bits is started in F72
format with frame 26. The first byte in XFIFO is transmitted in
the first time slot selected by TTR(4:1) and so on.
After receiving a complete multiframe in the time slot mode
(RTR(4:1)) an ISR0.RME interrupt is generated, if no HDLC or
BOM mode is enabled. In DL-bit access (CCR1.EDLX/
EITS = 10) XMFA is not valid.
XMFS interval time should not be changed, otherwise the
XFIFO data has to be retransmitted.
