J16 LIN_RX LIN RX enable
J17 LIN_TX LIN TX enable
3.5 Ethernet Configuration
The EVB is fitted with a standard RJ45 Ethernet connector (J7) and a DP83848C 10/100
Ethernet transceiver (U6).
By default, the Ethernet interface is enabled. The Ethernet interface the jumpers are detailed in
Table

3.6 User Area
There is a rectangular prototype area on the EVB top right corner, consisting of a 0.1in. pitch array of
through-hole plated pads. Power from all the three switching regulators is readily accessible along
with GND through JP1 – JP16 next to the prototyping area. This area is ideal for the addition of any
custom circuitry.
