Bits 7 to 0: Alternating Word Count Rate Bits 7 to 0 (ACNT[7:0]). When the BERT is programmed in the
alternating word mode, the words will repeat for the count loaded into this register then flip to the other word and
again repeat for the number of times loaded into this register. ACNT0 is the LSB of the 8-bit alternating word count
rate counter.
