Bits 7 to 5: Error Insert Bits 2 to 0 (EIB[2:0]). Will automatically insert bit errors at the prescribed rate into the
generated data pattern. Can be used for verifying error detection features. See
Table 9-23. BERT Error Insertion Rate
Bit 4: Single Bit Error Insert (SBE). A low-to-high transition will create a single bit error. Must be cleared and set
again for a subsequent bit error to be inserted.
Bits 3 to 0: Repetitive Pattern Length Select 3 to 0 (RPL[3:0]). RPL0 is the LSB and RPL3 is the MSB of a
nibble that describes 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 fewer 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). See
Table 9-24. BERT Repetitive Pattern Length Select
