TCS3404, TCS3414 − Application Information: Software
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.
Figure 45:
One-Shot Integration (INTEG_MODE 10b) Falling Edge
Note(s):
1. ADC_EN must be toggled (i.e. from high to low and back to high again) before next integration cycle
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
When the INTEG_MODE field value is set to 11b, the device
integrates from the rising edge of the first pulse until the rising
or falling edge of a subsequent pulse as specified by the SYNC_
EDGE and PARAM field values. See example timing diagrams
below. ADC_EN must be toggled (i.e. from high to low and back
to high again) before the next integration cycle. With this device
feature, the SYNC IN input pin can be used to synchronize the
device with an external light source (e.g. LED).
