14.5 Standard I/O pin configuration

Figure 23 shows the possible pin modes for standard I/O pins with analog input function:

• Digital output driver

• Digital input: Pull-up enabled/disabled

• Digital input: Pull-down enabled/disabled

• Analog input (for ADC input channels)

The default configuration for standard I/O pins is input with pull-up enabled. The weak

MOS devices provide a drive capability equivalent to pull-up and pull-down resistors.
