Bits [0]:
Statistic Counter Enable (Default 0)
0 – Disable
1 – Enable (all ports)
When statistic counter is enable, an interrupt control frame is generated to
the CPU, every time a counter wraps around. This feature requires an
external CPU.
Bits [1]:
Rate Control Enable (Default 0)
0 – Disable
1 – Enable; Must also set ECR2Pn[3] = 1
This bit enables/disables the rate control for all 10/100 ports. To start rate
control in a 10/100 port the rate control memory must be programmed. This
feature requires an external CPU. See Programming QoS Registers
Application Note and Processor Interface Application Note for more
information.
Bit [2]:
Support DS EF Code. (Default 0)
0 – Disable
1 – Enable (all ports)
When 101110 is detected in DS field (TOS[7:2]), the frame priority is set for
110 and drop is set for 0.
