Table 19.
When switching from input to output mode, the DR register has to be written first to drive the
correct level on the pin as soon as the port is configured as an output.
Alternate functions
When an on-chip peripheral is configured to use a pin, the alternate function is automatically
selected. This alternate function takes priority over the standard I/O programming under the
following conditions:
●
●
Input pull-up configuration can cause unexpected value at the input of the alternate
peripheral input.
When an on-chip peripheral use a pin as input and output, this pin has to be configured in
input floating mode.
When the signal is coming from an on-chip peripheral, the I/O pin is automatically
configured in output mode (push-pull or open drain according to the peripheral).
When the signal is going to an on-chip peripheral, the I/O pin must be configured in
floating input mode. In this case, the pin state is also digitally readable by addressing
the DR register.
