Synchronization
There are two basic modes of operation for controlling
synchronization: (1) internally timed, and (2) externally timed.
Internally-timed integration cycles can either be continuous
back-to-back conversions or can be externally triggered as a
single event using the SYNC pin. Externally-timed integrations
can be controlled by setting and clearing the ADC Enable in the
Control Register using the serial interface, or by one or more
pulses input to the SYNC pin. Internally-timed integration cycle
times are dependent on the PARAM field value and the internal
clock frequency. Nominal integration times and respective
scaling between integration times scale proportionally as
shown in the PARAM field in Figure 37. See Operating
Characteristics Table notes for detailed information regarding
how the scale values were obtained.
If a particular integration time period is required that is not
listed in the PARAM Integration Time field value, then the
manual timing control feature can be used to manually start
and stop the integration time period by setting
INTEG_MODE=01b. Manual integration is performed as follows:

Document Feedback
1. Disable ADC_EN (= 0) before initiating a manual
integration cycle
2. Clear and enable INTR before each cycle
3. Write 01b to INTEG_MODE field
4. Set ADC_EN (= 1) to start integration
5. Clear ADC_EN (= 0) to stop integration
6. Read channel data
