6.6.3 Multiplexing Digital Bidirectional Peripheral

The following conditions are characteristics of a multiplexed digital bidirectional peripheral:

• The peripheral automatically configures the pin as an output but not as an input. Some peripherals require the pin to be configured as an input by setting the corresponding TRISx bit = 1.
• Peripherals control output data.
• The pin output driver type can be affected by the peripheral (for example, drive strength, slew rate and so on).
• The PORTx register data input path is not affected and can read the pin value.
• PORTx register output data has no effect.
