Table 8. I/O Configurations
Notes:
1. When the I/O port is in input configuration and the associated alternate function is enabled as an output,
2. When the I/O port is in output configuration and the associated alternate function is enabled as an input,
3. For true open drain, these elements are not implemented.
40/172
reading the DR register will read the alternate function output status.
the alternate function reads the pin status given by the DR register content.
