6.6.1 Multiplexed Digital Input Peripheral
The following conditions are characteristics of a multiplexed digital input peripheral:
- Peripheral does not control the
TRISx register. Some peripherals require the pin be configured as an input by
setting the corresponding TRISx bit =
1
. - Peripheral input path is independent of I/O input path and uses an input buffer that is dependent on the peripheral.
- PORTx register data input path is not affected and can read the pin value.
