DT CMP Interrupt Problem

[Pic2008]

I don't have 16F877A now. If I continue to use 16F877, what is the best method to detect IN1>IN2?

This means I don't have any interrupt, and I have to poll the go/done bit in ADCON0 while sacrificing on executing other task?

The A/D module has an interrupt that fires when a conversion is complete.

You don't have to sit in a loop polling the Go/Done bit.

Oh, that's great. How do I implement this using DT interrupt?
Below is what I'm currently doing, using pause 25ms before the next AD.

define OSC 20      

' Define ADCIN parameters
Define  ADC_BITS        10     	' Set number of bits in result
Define  ADC_CLOCK       3     	' Set clock source (3=rc)
Define  ADC_SAMPLEUS    50    	' Set sampling time in uS


ADCON1= %00000111      'PIC16F877 all analog input except RE1,RE2

 'start AD here 
        ADCIN 0, adval				' Read channel0 RA.0 to adval
        pause 25
        ADCIN 1, adval2				' Read channel1 RA.1 to adval
        pause 25
