Bits 0 to 7: Alternating Word Count Rate (AWC[7:0]). When the BERT is programmed in the alternating word
mode, it transmits the word in register RP[15:0] a number of times equal to AWC[7:0] + 1 and then transmits the
word loaded in RP[31:16] the same number of times. The valid count range is from 00h to FFh. These bits are
ignored if the BERT is programmed for a pseudorandom pattern or a repetitive pattern.

Bit 0: Synchronization Status (SYNC). This real-time status bit is set when the incoming pattern matches for 32
consecutive bit positions. SYNC bit is cleared when six or more bits out of 64 are received in error.
Bit 1: BERT Error-Counter Overflow (BECO). This real-time status bit is set when the 24-bit BERT error counter
(BEC) saturates. BECO is cleared when BCR1:LC is toggled to load the error counts.
Bit 2: BERT Bit-Counter Overflow (BBCO). This real-time status bit is set when the 32-bit BERT bit counter
(BBC) saturates. BBCO is cleared when BCR1:LC is toggled to load the error counts.
Bit 4: Receive All Zeros (RA0). This real-time status bit is set when 32 consecutive 0s are received. RA0 is
cleared when a 1 is received.
Bit 5: Receive All Ones (RA1). This real-time status bit is set when 32 consecutive 1s are received. RA1 is
cleared when a 0 is received.
