Figure 27. Alternate function configuration
8.3.12 Analog configuration
When the I/O port is programmed as analog configuration:
• The output buffer is disabled
• The Schmitt trigger input is deactivated, providing zero consumption for every analog
value of the I/O pin. The output of the Schmitt trigger is forced to a constant value (0).
• The weak pull-up and pull-down resistors are disabled by hardware
• Read access to the input data register gets the value “0”
Figure 28 shows the high-impedance, analog-input configuration of the I/O port bit.
