PURPOSE:To supply a microcomputer which can designate the number of the terminals of a real time output port used for the control of a unit connected to an external part, in which the waste of hardware is reduced and an application field is wide because remaining terminals can be used for the other purpose by selecting a trigger signal designating the output timing of data outputted from the real time output port. CONSTITUTION:The computer consists of plural output latches 308, plural trigger signals 110 and ill designating data output timing, plural port latches 309 into which a value held by the output latches is written by the trigger signals and trigger signal selection circuits 106-109 selecting the plural trigger signals. |
