BAWC: BERT Alternating Word Count Rate. (Address = 44 Hex)
ALTCNT7 ALTCNT6 ALTCNT5 ALTCNT4 ALTCNT3 ALTCNT2 ALTCNT1 ALTCNT0
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.
BRP0: BERT Repetitive Pattern Set Register 0 (Address = 45 Hex)
BRP1: BERT Repetitive Pattern Set Register 1 (Address = 46 Hex)
BRP2: BERT Repetitive Pattern Set Register 2 (Address = 47 Hex)
BRP3: BERT Repetitive Pattern Set Register 3 (Address = 48 Hex)
BERT Repetitive Pattern Set. These registers must be properly loaded for the BERT to properly
generate and synchronize to a repetitive pattern, a pseudorandom pattern, alternating word pattern, or a
Daly pattern. For a repetitive pattern that is less than 32 bits, then the pattern should be repeated so that
all 32 bits are used to describe the pattern. For example if the pattern was the repeating 5-bit pattern
…01101… (where the right most bit is the one sent first and received first) then BRP0 should be loaded
with ADh, BRP1 with B5h, BRP2 with D6h,
pseudorandom pattern, all four registers should be loaded with all 1’s (i.e. xFF). For an alternating word
pattern, one word should be placed into BRP0 and BRP1 and the other word should be placed into BRP2
and BRP3. For example, if the DDS stress pattern "7E" is to be described, the user would place 00h in
BRP0, 00h in BRP1, 7Eh in BRP2, and 7Eh in BRP3 and the alternating word counter would be set to 50
(decimal) to allow 100 bytes of 00h followed by 100 bytes of 7Eh to be sent and received.
