Table 13. I/O Port 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,
48/265
reading the DR register will read the alternate function output status.
