TAOS137A − APRIL 2011
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.
