Bits 15 to 0: BERT Seed/Pattern (BSP[31:16]) - Upper 16 bits of 32 bits.
BERT Seed/Pattern (BSP[31:0]) – These 32 bits are the programmable seed for a transmit PRBS pattern, or the
programmable pattern for a transmit or receive repetitive pattern. BSP(31) will be the first bit output on the transmit
side for a 32-bit repetitive pattern or 32-bit length PRBS. BSP(31) will be the first bit input on the receive side for a
32-bit repetitive pattern.

Bits 5 to 3: Transmit Error Insertion Rate (TEIR[2:0]) – These three bits indicate the rate at which errors are
inserted in the output data stream. One out of every 10
of 0 disables error insertion at a specific rate. A TEIR[2:0] value of 1 result in every 10
TEIR[2:0] value of 2 result in every 100
a TEIR[2:0] value that is nonzero. If this register is written to during the middle of an error insertion process, the
new error rate will be started after the next error is inserted.
