Data Sheet
ELC
TCDE
AFX
Enable Length Check
This bit is only valid in HDLC SS7 mode:
If the number of received octets exceeds 272 + 7 within one Signaling
Unit, reception is aborted and bit RSTA.RAB is set.
ELC=’0’
ELC=’1’
Termination Character Detection Enable
This bit is valid in ASYNC/BISYNC modes only and enables/disables the
termination character detection mechanism:
TCDE = ’0’
TCDE = ’1’
Automatic FISU Transmission
This bit is only valid in HDLC SS7 mode:
After the contents of the transmit FIFO (XFIFO) has been transmitted
completely, FISUs are transmited automatically. These FISUs contain
the FSN and BSN of the last transmitted Signaling Unit (provided in
XFIFO).
AFX=’0’
AFX=’1’
Length Check disabled.
Length Check enabled.
No receive termination character detection is performed.
The termination character detection is enabled. The
receive data stream is monitored for the occurence of a
termination character (TC) programmed via register TCR.
When this character is detected, a ’TCD’ interrupt is
generated to the CPU (unless masked).
Note: If the programmed character length (bit field
