The internal weak pull-up resistor is defined in the following equation:
Figure 3: Internal Weak Pull-Up Resistor
Minimum condition: –40°C; VCCIO = VCC + 5%; VI = VCC + 5% – 50mV;
Typical condition: 25°C; VCCIO = VCC; VI = 0 V;
Maximum condition: 125°C; VCCIO = VCC – 5%; VI = 0 V;
where VI refers to the input voltage at the I/O pin.
