I/O Lines and Connections

Using the I/O lines of the peripheral requires configuration of the I/O pins.

Table 1. I/O Lines
Instance	Signal	I/O Line	Peripheral Function
DAC0	OUT	PA6	A

The DAC0 has one analog output pin (OUT) that must be configured before it can be used.

A DAC is also internally connected to the AC and to the ADC. To use this internal OUT as input, both output and input must be configured in their respective registers.

Note: Only DAC0 has an output driver for an external pin.
