NAME AND DESCRIPTION
ESMDM
CCR3.7
Elastic Store Minimum Delay Mode. See Section 10.3 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
RSYSCLK and TSYSCLK have been applied and are stable.
Must be cleared and set again for a subsequent reset.
RLOS
CCR3.5
Function of the RLOS/LOTC Output.
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).
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
-
CCR3.0
Not Assigned. Must be set to 0 when written
LOOP CODE GENERATION
When either the CCR3.1 or CCR3.2 bits are set to one, the DS21Q41B will replace the normal
transmitted payload with either the Loop Up or Loop Down code respectively. The DS21Q41B will
overwrite the repeating loop code pattern with the framing bits. The SCT will continue to transmit the
loop codes as long as either bit is set. It is an illegal state to have both CCR3.1 and CCR3.2 set to 1 at the
same time.
