Hi,

you might also be interested in the STE-FAQ, a little document that also covers the Blitter.
You can get it from http://paranoia.atari.org/projects/projects.html

BTW, since you also asked about accurate interrupt timing - this contradicts (a little) to using the Blitter. The Blitter will delay execution of an interrupt by up to 64 clockcycles in Blit-mode or as long as the Blitter takes in hog-mode.

If you want accurate execution of an interrupt, either use the Blitter only during the VBL and make sure it's done before the screen display starts, know its exact timing and fit your code around it - not easy and will probably not mean visible speed-up in comparison to a CPU copy - or simply use the CPU instead.
