The pattern generators and checkers are supported only for non-bonded channels. If original
design is bonded and you would like to use the PRBS generator/checker, you must read and
save the value in registers 0x119[0], 0x111[4:0] before changing the
x1_clock_source_sel settings to xN_non_bonding (by writing 5'b11000 to 0x119[0],
0x111[4:0]). This will change the design from bonded to non-bonded.
To disable the PRBS generator and restore the design back to original bonded design, you
need to restore the original value that was previously saved from registers 0x119[0],
0x111[4:0].
