Register Name:
LI.TIFGC
Register Description:
Transmit Inter-Frame Gapping Control Register
Register Address:
0C5h
Bit # 7 6 5 4 3 2 1 0
Name TIFG7 TIFG6 TIFG5 TIFG4 TIFG3 TIFG2 TIFG1 TIFG0
Default 0 0 0 0 0 0 0 1
Bits 0 - 7: Transmit Inter-Frame Gapping (TIFG[7:0]) – These eight bits indicate the number of additional flags
and bytes of inter-frame fill to be inserted between packets. The number of flags and bytes of inter-frame fill
between packets is at least the value of TIFG[7:0] plus 1. Note: If inter-frame fill is set to all 1’s, a TFIG value of 2
or 3 will result in a flag, two bytes of 1’s, and an additional flag between packets.
Register Name:
LI.TEPLC
Register Description:
Transmit Errored Packet Low Control Register
Register Address:
0C6h
Bit # 7 6 5 4 3 2 1 0
Name TPEN7 TPEN6 TPEN5 TPEN4 TPEN3 TPEN2 TPEN1 TPEN0
Default 0 0 0 0 0 0 0 0
Bits 0 – 7: Transmit Errored Packet Insertion Number (TPEN[7:0]) – These eight bits indicate the total number
of errored packets to be transmitted when triggered by TIAEI. Error insertion will end after this number of errored
packets have been transmitted. A value of FFh results in continuous errored packet insertion at the specified rate.
