I/O PORTS (Cont’d)
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,
2. When the I/O port is in output configuration and the associated alternate function is enabled as an input,
reading the DR register will read the alternate function output status.
the alternate function reads the pin status given by the DR register content.
