Description

TxData2_2

GMII/MII transmit data - bit 2

PriBndw0

I/Opu

Priority bandwidth configuration pins. These configuration pins allow

the bandwidth percentage assigned to a priority packet queue to be

modified to certain hardwired levels. PriBndw chooses between 4

hardwired spreading percentage schemes among the 4 priority

queues of each port.

PriBndw(0)is latched on reset

TxData2_1

GMII/MII transmit data - bit 1

PriClass[2] is latched on reset

PriClass2_1

I/Opd

Priority class - most significant bit.

TxData2_0

GMII/MII transmit data - least significant bit

PriClass0_0

I/Opu

Priority class - least significant bit. Sets priority level per port basis.

PriClass[2] - '00' - port 2 low priority

PriClass[2] - '01' - port 2 has normal priority

PriClass[2] - '10' - port 2 has high priority

PriClass[2] - '11' - port 2 has very high priority

PriClass[2] is latched on reset
