Macros
DAC Status Flags
DAC status flags, returned by dac_get_status() and cleared by dac_clear_status().
#define	DAC_STATUS_CHANNEL_0_EMPTY   (1UL << 0)
	Data Buffer Empty Channel 0 - Set when data is transferred from DATABUF to DATA by a start conversion event and DATABUF is ready for new data. More...
#define	DAC_STATUS_CHANNEL_0_UNDERRUN   (1UL << 1)
	Under-run Channel 0 - Set when a start conversion event occurs when DATABUF is empty. More...
