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:
1. Perform the necessary steps from steps 1 to 7 in Steps to Perform Dynamic
Reconfiguration.
2. Perform a read-modify-write to address 0x00A with a value of 1'b1 to bit[7].
3. Perform a read-modify-write to address 0x00B according to Register Map for PRBS
Checker for bonded and non bonded designs.
4. Perform a read-modify-write to address 0x00C according to Register Map for PRBS
Checker for bonded and non bonded designs.
5. Perform a read-modify-write to address 0x13F according to Register Map for PRBS
Checker for bonded and non bonded designs.
6. Perform a read-modify-write to address 0x111 according to Register Map for PRBS
Checker for bonded and non bonded designs.
7. Perform the necessary steps from steps 9 to 12 in Steps to Perform Dynamic
Reconfiguration.
To disable the PRBS verifier write the original values back into the read-modify-
write addresses listed above.
6.16.1.5. Disabling/Enabling PRBS Pattern Inversion
The default PRBS pattern is inverted for both PRBS generator and checker. You can
disable the pattern inversion for PRBS data leaving or entering the PRBS data pattern
generator and checker, respectively. Table 205 on page 368 shows the addresses and
bits to control the inversion of the PRBS generator or checker. To disable the PRBS
pattern inversion for the PRBS generator or checker, follow these steps:
