NAME AND DESCRIPTION
RZSE
CCR2.0
Receive FDL Zero Destuffer Enable. Set this bit to zero if
using the internal HDLC/BOC controller instead of the
legacy support for the FDL. See Section 19 for details.
0 = zero destuffer disabled
1 = zero destuffer enabled

NAME AND DESCRIPTION
RESMDM
CCR3.7
Receive Elastic Store Minimum Delay Mode. See Section
17 for details.
0 = elastic stores operate at full two frame depth
1 = elastic stores operate at 32–bit depth
TCLKSRC
CCR3.6
Transmit Clock Source Select. This function allows the
user to internally select RCLK as the clock source for the
transmit side formatter.
0 = Transmit side formatter clocked with signal applied at
TCLK pin. LOTC Mux function is operational (TCR1.7)
1 = Transmit side formatter clocked with RCLK.
RLOSF
CCR3.5
Function of the RLOS/LOTC Output. Active only when
FMS = 1 (DS21Q41 emulation).
0 = Receive Loss of Sync (RLOS)
1 = Loss of Transmit Clock (LOTC)
FMS is tied to ground for the DS21FF42/DS21FT42.
RSMS
CCR3.4
RSYNC Multiframe Skip Control. Useful in framing
format conversions from D4 to ESF. This function is not
available when the receive side elastic store is enabled.
0 = RSYNC will output a pulse at every multiframe
1 = RSYNC will output a pulse at every other multiframe
note: for this bit to have any affect, the RSYNC must be set
to output multiframe pulses (RCR2.4=1 and RCR2.3=0).
PDE
CCR3.3
Pulse Density Enforcer Enable.
0 = disable transmit pulse density enforcer
1 = enable transmit pulse density enforcer
ECUS
CCR3.2
Error Counter Update Select. See Section 12 for details.
0 = update error counters once a second
1 = update error counters every 42 ms (333 frames)
TLOOP
CCR3.1
Transmit Loop Code Enable. See Section 20 for details.
0 = transmit data normally
1 = replace normal transmitted data with repeating code as
defined in TCD register
