a. A bi-directional Transient Voltage Suppressor (TVS) device is included between 3.3V and
ground. Input/Output (I/O) lines are protected by TVS devices. Series resistance is included
for the following I/O lines: COM1/COM2/COM3 Tx and Rx, RESETIN, Event1 and
Event2. Lines that do not have series resistance include: CAN1_Tx, CAN1_Rx, CAN2_Tx,
CAN2_Rx, USB D (+) and USB D (-).
