Bits 28:24 – TRGSRC3[4:0] Trigger Source for Conversion of Analog Input AN3 Select bits

Note: For STRIG, in addition to setting the trigger, it also requires programming of the STRGSRC[4:0] bits (ADCCON1[20:16]) to select the trigger source, and requires the appropriate CSS bits to be set in the ADCCSSx registers.
