Notes

1 Unit of measurement is one link data bit time; at 10 Mbits/s data link speed, one bit time is nomi-

nally 100 ns.

2 Maximum time assumes there is no acknowledge packet already on the link. Maximum time with

acknowledge on the link is extended by 2 bits.

3 Both data transmission and the returned acknowledge must be completed before OutputInt can

go high.
