4.5 Conversion Triggering Mode

To fit all application needs, various methods are available to trigger a V_TEMP or V_BG conversion: a software start, a sequenced start with other channels, or a periodic start dedicated to temperature measurement. Refer to “Temperature Sensor” in the “Analog-to-Digital Converter (ADC) Controller” section of the SAMA7D6 Series data sheet, and adapt the ADC_TRGR.TRGMOD field to the required behavior.

Note: Considering that the V_BG/V_TEMP switch cannot be performed by the hardware sequencer, but only by a software write in ADCC_ACR.SRCLCH, selecting a software triggering mode to read the junction temperature is recommended.
