General Analog Input Only Structure
The analog-input-only configuration on general port pins is the default setting. For ADC or Analog
Comparator input application, user may keep the port setting in this configuration. If apply the port pin to
digital function, user must program the port pin to associated configuration. The analog-input-only port
configuration is shown in Figure 14
–5.

General Open-Drain Output with Pull-up Resistor Structure
The open-drain output with pull-up resistor configuration on general port pins enables the on-chip pull-up
resistor in open-drain output mode.
The open-drain output with pull-up resistor port configuration is shown in Figure 14

General Open-Drain Output Structure
The open-drain output configuration on general port pins is the same function as port 3 open-drain output
mode. The general open-drain port configuration is shown in Figure 14
–7.
