INTERRUPT
When the INTEG_MODE field value is set to 10b, an externally-controlled synchronization input (SYNC) is used
to trigger the start of an integration period. The integration period starts on the rising edge of the SYNC pulse,
triggers a single, internally-timed integration cycle, and continues until the Nominal Integration Time, as defined
in the PARAM field, is completed.
1. Enable ADC_EN (= 1)
2. Set PARAM for desired integration cycle (12ms, 100ms, or 400ms)
3. Set INTEG_MODE to 10b
4. Disable SYNC and clear INTR
5. Read channel data
