DS51456B-page 103 Return Value: None Remarks: This function clears the Interrupt Flag (ADIF) bit and then sets the interrupt priority and enables/disables the interrupt. Source File: ConfigIntADC10.c Code Example: ConfigIntADC10(ADC_INT_PRI_3 & ADC_INT_DISABLE); ConvertADC10 Description: This function starts the A/D conversion. Include: adc10.h Prototype: void ConvertADC10(void); Arguments: None Return Value: None Remarks: This function clears the ADCON1bit and thus stops sampling and starts conversion.
