Repetitive Pattern Length Configuration
RPL0 is the LSB and RPL3 is the MSB of a nibble that describes the how long the repetitive pattern is.
The valid range is 17 (0000) to 32 (1111). These bits are ignored if the receive BERT is programmed for
a pseudorandom pattern. To create repetitive patterns less than 17 bits in length, the user must set the
length to an integer number of the desired length that is less than or equal to 32. For example, to create a
6 bit pattern, the user can set the length to 18 (0001) or to 24 (0111) or to 30 (1101).
