PRODUCTION DATA
When operating in 10BASE-Te or 100BASE-TX mode, signals can be looped back after the analog front-end. Analog Loopback requires 100-Ω terminations accross pins #1 and #2 as well as 100-Ω terminations accross pins #3 and #6 at the RJ45.
Analog Loopback is enabled by setting bit[3] in the BISCR.
