Got to laugh - 16f690 ...absolute mare for a noobesque personage like meself..

I wouldn't mind but I've tackled so much with that PIC variant...but comparators? WTF?! The datasheet has ma heed buzzin.

I've decided a nice easy entry into the world of comparators is now going to be with a simpler 12F683. Once I nail the concepts with that, then I shall take a few swigs of stiff whisky & get out the 16F690 datasheet again - were microchip having a laugh with that on?
