The CMOS output drivers in the I/O pins intrinsically provide electrostatic discharge
(ESD) protection. There are two cases to consider for ESD voltage strikes: positive
voltage zap and negative voltage zap.
A positive ESD voltage zap occurs when a positive voltage is present on an I/O pin
due to an ESD charge event. This can cause the N+ (Drain)/ P-Substrate junction of
the N-channel drain to break down and the N+ (Drain)/P-Substrate/N+ (Source)
intrinsic bipolar transistor turn on to discharge ESD current from I/O pin to GND.
