Figure 3. Pullup and Pulldown Typical Resistor Values (VDD = 3.0 V)
Figure 4. Typical Low-Side Driver (Sink) Characteristics Low Drive (PTxDSn = 0)
Figure 5. Typical Low-Side Driver (Sink) Characteristics High Drive (PTxDSn = 1)
6 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.
7 Power supply must maintain regulation within operating V
DD range during instantaneous and operating maximum current
conditions. If positive injection current (VIn > VDD) is greater than IDD, the injection current may flow out of VDD and could result
in external power supply going out of regulation. Ensure external VDD 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).
