Typical values are measured at 25°C. Characterized, not tested.
When a pin interrupt is configured to detect rising edges, pull-down resistors are used in place of pull-up resistors.
The specified resistor value is the actual value internal to the device. The pull-up value may measure higher when measured
externally on the pin.
Power supply must maintain regulation within operating V
conditions. If positive injection current (V
in external power supply going out of regulation. Ensure external V
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).
All functional non-supply pins are internally clamped to V
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.
The RESET pin does not have a clamp diode to V
Maximum is highest voltage that POR will occur.
