The generic 14-pin CAN EVM has footprints on the PCB for the installation of various filtering and protection options to adapt the EVM to match CAN network topology requirements if the EVM is being used as a CAN node.
Each digital input or output pin has footprints allowing for series current-limiting resistors (default populated with 0Ω), pullup or down resistors (depending on pin use), and a capacitor to GND which allows for RC filters when configured with a series resistor. Table 2-6 lists these features for each of the digital input and output pins of the EVM. Replace or populate the RC components as necessary for the application.
