Note: 1 TSAn.m must be programmed to enable the port and timeslots selected by PNS (n = PNS) and ATSS (m = Timeslot).
The Datapath for an RXP Clock Only Bundle should not be released from Reset (B.BRCR2.RXBRE = 1). The Clock
Only Bundle does not include payload data. Holding the Bundle’s Datapath in Reset prevents the S132 from
attempting to process the packet after the packet header has been fully interpreted.
