This bit field does not control the digital input buffer. The digital input buffer for pin n (Pxn) can be configured in the Input/Sense Configuration (ISC) bit field in the Pin n Control (PORTx.PINnCTRL) register.
The available configuration for each bit n in this bit field is shown in the table below.
| Value | Description |
|---|---|
| 0 | Pxn is configured as an input-only pin, and the output driver is disabled |
| 1 | Pxn is configured as an output pin, and the output driver is enabled |
