2.3 Using Customer Installable I/O Options for Current Limiting, Pullup and Pulldown, Noise Filtering

The 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 pullup or down resistors (depending on pin use) and a capacitor to GND which allows for EMI/EMC filtering. Table 2-4 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.
