2. Description: Port pins that are programmed for push-pull output mode and a logic-high state (‘1’ written to
the port pin latch) may become forced to a logic-low state if exposed to an overvoltage condition that exceeds
the specified limits as posted in the data sheet (see "Absolute Maximum Specifications").
Impact: This can result in up to 40 mA of current consumption (per pin affected) from the on-chip voltage
supply, or higher than expected current consumption from an off-chip source connected to the pin due to the
low impedance path to ground. Revision F will fix this problem.
Workaround: Standard system level design practices to ensure port pins are protected from over voltage
conditions (i.e., conditions outside the specified limits in the data sheet) should be implemented, such as in-
series resistors (e.g., 100 ohm in-series resistor) and/or schottky protection diodes to prevent over voltage
conditions (e.g., BAT54S) for pins that are considered high risk (e.g., pins connected to signals that are
exposed to human contact off-board).
