21 Pin pull-up resistance values may be lower if an external source drives the pin higher than VCCIO.
22 R_PU = (VCCIO – VI)/IR_PU
Minimum condition: –40°C; VCCIO = VCC + 5% , VI = VCC + 5% – 50 mV;
Typical condition: 25°C; VCCIO = VCC, VI = 0 V;
Maximum condition: 100°C; VCCIO = VCC – 5% , VI = 0 V; in which VI refers to the input voltage at the I/O pin.
23 R_PD = VI/IR_PD
Minimum condition: –40°C; VCCIO = VCC + 5% , VI = 50 mV;
Typical condition: 25°C; VCCIO = VCC, VI = VCC – 5% ;
Maximum condition: 100°C; VCCIO = VCC – 5% , VI = VCC – 5% ; in which VI refers to the input voltage at the I/O pin.
