Bit 6: Priority Table Port Access Address (PTPAA). This bit is an extension of the PTAA[6:1] bits, but is used to
divide between Priority lookups for Ethernet (LAN) Port 1 (PTPAA = 0) and Ethernet (LAN) Port 2 (PTPAA = 1). Not
valid for devices with only one Ethernet port.
Bits 0-5: Priority Table Access Address (PTAA [6:1]). These bits provide the Priority Table Address for a uP
Read or Write operation. The address into the priority table is used to resolve VLAN 802.1p PCP and DSCP to the
four priority levels. When using PCP priority mode, only addresses PTAA[3:1] are used. The priority mode for each
Ethernet port can be independently selected using the SU.LP1C and SU.LP2C registers.
