Note: Bits that are underlined are read only; all other bits are read-write.
Bit 0 / Force Resynchronization (RESYNC). A low to high transition will force the receive BERT
synchronizer to resynchronize to the incoming data stream. This bit should be toggled from low to high
whenever the Host wishes to acquire synchronization on a new pattern. Must be cleared and set again for
a subsequent resynchronization.
Bit 1 / Load Bit and Error Counters (LC). A low to high transition latches the current bit and error
counts into the Host accessible registers BERTBC and BERTEC and clears the internal count. This bit
should be toggled from low to high whenever the Host wishes to begin a new acquisition period. Must be
cleared and set again for a subsequent loads.
Bits 2 to 4 / Pattern Select Bits 0 (PS0 to PS2).
000 = Pseudorandom Pattern 2^7 – 1 (ANSI T1.403-1999 Annex B)
001 = Pseudorandom Pattern 2^11 – 1 (ITU O.153)
010 = Pseudorandom Pattern 2^15 – 1 (ITU O.151)
011 = Pseudorandom Pattern QRSS (2E20 - 1 with a one forced if the next 14 positions are zero)
100 = Repetitive Pattern
101 = Alternating Word Pattern
110 = illegal state
111 = illegal state
