Bits 8 to 11: Repetitive Pattern Length Bits 5 (RPL0 to RPL3). 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).
Bit 13: Interrupt Enable for Counter Overflow (IEOF). Allows the receive BERT to cause an interrupt if either
the Bit Counter or the Error Counter overflows (
Bit 14: Interrupt Enable for Bit Error Detected (IEBED). Allows the receive BERT to cause an interrupt if a bit
error is detected
Bit 15: Interrupt Enable for Change of Synchronization Status (IESYNC). Allows the receive BERT to cause
an interrupt if there is a change of state in the synchronization status (i.e., the receive BERT either goes into or out
of synchronization) (
