Sixteen Local Input Channel Delay Registers (LCDR0 to LCDR15) allow users to program the input channel delay
for the Local input data streams LSTi0-15. The maximum possible adjustment is 511 channels and the LCDR0 to
LCDR15 registers are configured as follows:
Non-32 Mbps Mode, n = 0 to 7

Start Bit Error Rate Receiver for Local
A LOW to HIGH transition enables the Local BER receiver. The receiver
monitors incoming data for reception of the seed value. When detected, the
LOCK state is indicated (LOCKL), the receiver compares the incoming bits with
the reference generator for bit equality, and increments the Local Bit Error
Register (LBCR) on each failure.
When LOW, bit comparison is disabled and the error count is frozen.
Start Bit Error Rate Transmitter for Local
A LOW to HIGH transition enables the Local BER transmission.
When LOW, Local transmission is disabled.
BER Mode Select for Local
When HIGH, a PRBS sequence of length 2
When LOW, a PRBS sequence of length 2
