Bus Time Stamp at which Last Packet was Received [31:16]
Bus Time Stamp at which Last Packet was Received [15:0]
This field contains the desired local/remote time stamp delta that should be
applied to all received packets. A time stamp delta of zero means that a packet
received with time stamp of zero would see its first byte output on the bus when
the local bus time stamp is zero. This field should be written to zero at
initialization time.
Write 0 for normal operation.
all remote/local time stamp deltas are calculated with the following equation:
delta = remote_packet_timestamp - local_bus_timestamp;
