Bit 7: Priority Table Initialization Status (PTIS): This bit is set when the Priority Table initialization has been
completed.
Bit 6: Priority Table Port Shadow Address (PTSAA). This bit is an extension of the PTSA [6:1] bits, but is used
to divide between Priority lookups for LAN Port 1 (PTSAA = 0) and LAN Port 2 (PTSAA = 1).
Bits 0-5: Priority Table Shadow Address (PTSA [6:1]). This register interfaces directly to the Priority Table
memory block to provide the selected Priority Table Address that is to be used for each Priority Table operation
(LAN Trap, WAN Trap or uP Read/Write). When PTAIM = 1, the Shadow Address automatically increments for
each updated Read and/or Write Priority Table Access Address.
