Note: Once the DAC channelx is enabled, the corresponding GPIO pin (PA4) is automatically
connected to the analog converter output (DAC1_OUT). In order to avoid parasitic
consumption, the PA4 or PA5 pin should first be configured to analog (AIN).

DAC channel enable

The DAC channel can be powered on by setting the EN1 bit in the DAC_CR register. The
DAC channel is then enabled after a startup time t
