GENERAL DESCRIPTION

EM56000A is a series of single chip dual channel IC with voice synthesizer. The dual channel can be (voice +
voice) simultaneously. That contains some input and I/O ports, and a tiny controller. By programming through the
tiny controller, user's application including section combination, trigger modes, control outputs, IR communication,
and other logical function can be easily implemented.
