ABSTRACT:
A controller integrated circuit, such as a cathode ray tube controller, constituting a part of a microcomputer system comprises a plurality of internal registers, a designating register to which data designating at least one of the internal registers is set, a selection circuit selecting one of the internal registers by the data of the designating register, a first external terminal to which the data of the register selected by the selection circuit is supplied, and a second external terminal to which a timing signal representing the timing of the data supplied to the first external terminal is supplied. According to this circuit construction, the data inside the controller integrated circuit can be easily referred to be the control of the first register and by use of the first and second external terminals.
