NAME AND DESCRIPTION
ESMDM
CCR3.7
Elastic Store Minimum Delay Mode. See Section 11 for
details.
0=elastic stores operate at full two-frame depth
1=elastic stores operate at 32-bit depth
ESR
CCR3.6
Elastic Store Reset. Setting this bit from a 0 to a 1 will force
the elastic stores to a known depth. Should be toggled after
SYSCLK has been applied and is stable. Must be cleared and
set again for a subsequent reset.
P16F
CCR3.5
Function of Pin 16.
0 = Receive Loss of Sync (RLOS).
1 = Loss of Transmit Clock (LOTC).
RSMS
CCR3.4
RSYNC Multiframe Skip Control. Useful in framing format
conversions from D4 to ESF.
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) and the
receive elastic store must be bypassed. (CCR1.2 = 0).
PDE
CCR3.3
Pulse Density Enforcer Enable.
0 = disable transmit pulse density enforcer
1 = enable transmit pulse density enforcer
TLD
CCR3.2
Transmit Loop Down Code (001).
0 = transmit data normally
1 = replace normal transmitted data with Loop Down code
TLU
CCR3.1
Transmit Loop Up Code (00001).
0 = transmit data normally
1 = replace normal transmitted data with Loop Up code
LIRST
CCR3.0
Line Interface Reset. Setting this bit from a 0 to a one will
initiate an internal reset that affects the slicer, AGC, clock
recovery state machine and jitter attenuator. Normally this bit is
only toggled on power-up. Must be cleared and set again for a
subsequent reset.
