NAME AND DESCRIPTION
Elastic Store Minimum Delay Mode. See Section
details.
0 = elastic stores operate at full two-frame depth
1 = elastic stores operate at 32-bit depth
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.
Function of the RLOS/LOTC Output.
0 = Receive Loss of Sync (RLOS)
1 = Loss of Transmit Clock (LOTC)
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).
Pulse Density Enforcer Enable.
0 = disable transmit pulse density enforcer
1 = enable transmit pulse density enforcer
Error Counter Update Select. See Section
0 = update error counters once a second
1 = update error counters every 42ms (333 frames)
Transmit Loop Code Enable. See Section
0 = transmit data normally
1 = replace normal transmitted data with repeating code as
defined in TCD register
Not Assigned. Must be set to 0 when written.
