Note:
Bits that are underlined are read-only; all other bits are read-write.
Bits 0 to 31/BERT Repetitive Pattern Set (RP0 TO RP31).
RP0 is the LSB and RP31 is the MSB.
These registers must be properly loaded for the BERT to properly generate and synchronize to either a
repetitive pattern, a pseudorandom pattern, or an alternating word pattern. For a repetitive pattern that is
fewer than 17 bits, 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 1, sent first
and received first), then BERTRP0 should be loaded with xB5AD and BERTRP1 should be loaded with
x5AD6. For a pseudorandom pattern, both registers should be loaded with all 1’s (i.e., xFFFF). For an
alternating word pattern, one word should be placed into BERTRP0 and the other word should be placed
into BERTRP1. For example, if the DDS stress pattern “7E” is to be described, the user would place
x0000 in BERTRP0 and x7E7E in BERTRP1 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.
