Interrupt 0 status. Interrupt 0 contains FIFO fill level, descriptor status and ADC range under/overflow
| FIFO_FULL | 0: number of samples in FIFO less than or equal to FIFO_LEVEL 1: number of samples in FIFO is more than FIFO_LEVEL |
| FIFO_EMPTY | 0: FIFO is not empty 1: FIFO is empty |
| FIFO_OVERFLOW | FIFO was full; conversion sample is not stored and lost |
| DSCR_DONE | The descriptor INTERRUPT field was enabled and its sample is converted. |
| DSCR_ERROR | The ADC was not fully woken up when a sample was converted and the conversion results is unreliable |
| ADC_OVF | Converted sample value was over range of the 12 bit output code. |
| ADC_UNF | Converted sample value was under range of the 12 bit output code. |
