Bits 0 to 31: BERT Repetitive Pattern (RP[31:0]). These registers must be configured for the BERT to properly
generate and synchronize to a repetitive pattern or an alternating word pattern. For an alternating word pattern, the
first word to be transmitted should be placed into RP[15:0], and the second word should be placed into RP[31:16].
In the first word, RP0 is the LSB and is transmitted first. In the second word, RP16 is the LSB and is transmitted
first. For repetitive patterns, RP0 is the LSB and is transmitted first, while the MSB is determined by the repetitive
pattern length, RPL[3:0].
An alternating word example: To use the DDS stress pattern “7E,” set BRPR1 = BRPR2 = 00h, BRPR3 = BRPR4 =
7Eh. When AWC[7:0] is set to 49 (decimal), the BERT sends and detects (49 + 1) x 2 = 100 bytes of 00h followed
by 100 bytes of 7Eh.
