               CE026 - dsPIC SMPS ADC Early Interrupt
               --------------------------------------

The dsPIC SMPS Family of Digital Signal Controllers feature an on-chip 
10-bit 2 MSPS A/D Converter. The module is designed to trigger and convert
Analog Channels in pairs. The Early interrupt feature allows an interrupt
to be generated immediately after the first conversion of the pair is
completed.

This code example sets up ADC  pair 0 (AN1,AN0) conversion to be triggered 	
by software trigger. The Early Interrupt feature is enabled. In this example,
the FRC with Hi-Range is set up to run at  frequency of 14.55MHz. This will
result in Fcy = 29.1 MHz.   The input clock to the ADC  clock divider will be

Tcy = 34.364 nsec  													
Time required for one conversion  = 721.64 nsec						

The first end-of-conversion is detected by the ADC interrupt while the 
second end-of-conversion is detected by polling the PEND0 bit in the ADPC0
register.Fadc = 232.8 MHz.
