Thirty-two Backplane Output 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 Backplane 32 Mbps Mode in the Control Register (via the
MODE32B bit), in which case, Backplane output streams 0-15 will operate at 32 Mbps and Backplane output
streams 16-31 will be unused. The BOBRR registers are configured as follows:
