Table 9. I/O Configurations
Notes:
1. When the I/O port is in input configuration and the associated alternate function is enabled as an output, reading the
DR register reads the alternate function output status.
2. When the I/O port is in output configuration and the associated alternate function is enabled as an input, the alternate
function reads the pin status given by the DR register content.
