1. Typical values are at 25 °C and are for design aid only; not guaranteed and not subject to production
2. “BT” signifies bit times at the line rate (that is, BT = 100 ns if using 10BASE-T, BT = 10 ns if using

The table latency values are derived with the hardware configuration pins FIFOSEL[1:0] set at a
default configuration of 00 (32 bits of initial fill).
