  • Nice little features that can be used to solve unexpected problems.

    Anything the processor can do automatically represents a possibility that it may later be used in unconventional ways.

    For example the link Andy posted a couple of months ago (or if it was on 8052.COM) about using an AVR chip to create a video demo and using an SPI controller to overlay high-resolution text on the video signal.
