mode – Analog to digital mode. The valid options vary depending on the device.
See the devices .h file for all options. Some typical options include:
· ADC_OFF
· ADC_CLOCK_DIV_1
· ADC_HALT_IDLE – The ADC will not run when PIC is idle.
Undefined
Configures the High-Speed ADC clock speed and other High-Speed ADC
options including, when the ADC interrupts occurs, the output result format, the
conversion order, whether the ADC pair is sampled sequentially or
simultaneously, and whether the dedicated sample and hold is continuously
sampled or samples when a trigger event occurs.
Only on dsPIC33FJxxGSxxx devices.
Constants are define in the device .h file.
