14.11.5
Address 00CC
Backplane BER Count Register contains the number of counted errors. This register is read-only.
The BBCR register is configured as follows:
14.12
14.12.1
Addresses 00CD
Sixteen Local Input Bit Rate Registers allow the bit rate for each individual stream to be set to 2, 4, 8 or 16 Mbps.
These registers may be overridden by setting Local 32 Mbps Mode in the Control Register (via the MODE32L bit),
in which case, Local input streams 0-7 will operate at 32 Mbps and Local input streams 8-15 will be unused.
The LIBRR registers are configured as follows:
