I²C Address 02A, CPU Address:h102
Accessed by CPU and I²C (R/W)
This register indicates the legal egress ports. A “1” on bit 3 means that the packet can be sent to port 3. A “0” on bit
3 means that any packet destined to port 3 will be discarded. This register works with registers 1 to form a 10 bit
mask to all egress ports.

0 - Disable. All frames are analysed. Transmit Priority and Discard Priority are
based on VLAN Tag, TOS or Logical Port.
1 - Enable. Transmit Priority and Discard Priority are based on values
programmed in bit [6:3]
