I/O PORTS (Cont’d)

Table 10. 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,

reading the DR register will read 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.
