NOTES:
1. RAM will retain data down to POR voltage. RAM data not guaranteed to be valid following a POR.
2. This parameter is characterized and not tested on each device.
3. If SAFE bit is set, VDD must be above re-arm voltage to allow MCU to accept interrupts, refer to 5.6 Low-Voltage Detect 4. Measurement condition for pull resistors: VIn = VSS for pullup and VIn = VDD for pulldown.
5. The PTA0 pullup resistor may not pull up to the specified minimum VIH. However, all ports are functionally tested to
guarantee that a logic 1 will be read on any port input when the pullup is enabled and no dc load is present on the pin. In
addition, the test checks that the pin is pulled up from VSS to a logic 1 within 20 s with a nominal capacitance of 75 pF.
6. All functional non-supply pins are internally clamped to VSS and VDD.
7. Input must be current limited to the value specified. To determine the value of the required current-limiting resistor,
calculate resistance values for positive and negative clamp voltages, then use the larger of the two values.
