NAME AND DESCRIPTION
TESE
CCR3.7
Transmit Elastic Store Enable.
0 = elastic store is disabled
1 = elastic store is enabled
TCBFS
CCR3.6
Transmit Channel Blocking Registers (TCBR) Function
Select.
0 = TCBRs define the operation of the TCHBLK output pin
1 = TCBRs define which signaling bits are to be inserted
TIRFS
CCR3.5
Transmit Idle Registers (TIR) Function Select.
0 = TIRs define in which channels to insert idle code
1 = TIRs define in which channels to insert data from RSER
ESR
CCR3.4
Elastic Stores Reset. Setting this bit from a 1 to a 0 will force
the elastic stores to a known depth. Should be toggled after
SYSCLK has been applied and is stable. Must be set and cleared
again for a subsequent reset. Do not leave this bit set high.
LIRST
CCR3.3
Line Interface Reset. Setting this bit from a 0 to a 1 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.
CCR3.2
Not Assigned. Should be set to 0 when written.
TSCLKM
CCR3.1
Transmit Backplane Clock Select. Must be set like RCR2.2.
0 = 1.544MHz
1 = 2.048MHz
CCR3.0
Not Assigned. Should be set to 0 when written.
