Use the PRBS soft accumulators to count the number of accumulated bits and errors
when the hard PRBS blocks are used. For more details about using the accumulators
and reading the error values, refer to the "PRBS Soft Accumulators" section.

6.16.1.4. Enabling the PRBS Checker in bonded designs
You must perform a sequence of read-modify-writes to addresses 0x00A, 0x00B,
0x00C, 0x13F, 0x111 and to enable the PRBS data checker in bonded designs. To
enable the PRBS checker, follow these steps:
