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, V_DD must be above re-arm voltage to allow MCU to accept interrupts, refer to 5.6 Low-Voltage Detect
(LVD) System.
4. Measurement condition for pull resistors: V_In = V_SS for pullup and V_In = V_DD for pulldown.
5. The PTA0 pullup resistor may not pull up to the specified minimum V_IH. 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 V_SS to a logic 1 within 20 µs with a nominal capacitance of 75 pF.
6. All functional non-supply pins are internally clamped to V_SS and V_DD.
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.
8. Power supply must maintain regulation within operating V_DD range during instantaneous and operating maximum current
conditions. If positive injection current (V_In > V_DD) is greater than I_DD, the injection current may flow out of V_DD and could
result in external power supply going out of regulation. Ensure external V_DD load will shunt current greater than maximum
injection current. This will be the greatest risk when the MCU is not consuming power. Examples are: if no system clock
is present, or if clock rate is very low (which would reduce overall power consumption).
9. PTA0 does not have a clamp diode to V_DD. Do not drive PTA0 above V_DD.
