Note:
Bits that are underlined are read-only; all other bits are read-write.
Bit 0/Transmit Pattern Load (TC).
A low-to-high transition loads the pattern generator with the
repetitive or pseudorandom pattern that is to be generated. This bit should be toggled from low to high
whenever the host wishes to load a new pattern. Must be cleared and set again for subsequent loads.
Bit 4/Single Bit-Error Insert (SBE).
A low-to-high transition creates a single bit error. Must be cleared
and set again for a subsequent bit error to be inserted.
Bit 5/Error Insert Bit 0 (EIB0), Bit 6/Error Insert Bit 1 (EIB1), Bit 7/Error Insert Bit 2 (EIB2).
Automatically inserts bit errors at the prescribed rate into the generated data pattern. Useful for verifying
error-detection operation.

Bits 8 to 15/Alternating Word Count Rate (AWC0 to AWC7).
When the BERT is programmed in the
alternating word mode, the word in BERTRP0 is transmitted for the count loaded into this register plus
one, then flips to the other word loaded in BERTRP1 and again repeats for the same number of times. The
valid count range is from 00h to FFh.
