Abstract
In a microcomputer according to the present invention, output pulse levels are stored in bit coles corresponding to respective addresses of a memory circuit which are outputted from a timer circuit which uses a clock as a count source, and each bit output of the memory circuit is latched in synchronism with the clock and outputted to a port output circuit, so as to obtain a plurality of desired phase pulses having different cycles.
Claims4
A microcomputer comprising:
- a timer circuit having a clock as a count source;
- a memory circuit to store output pulse waveforms represented as bit strings;
- wherein said bit strings correspond to respective addresses output from said timer circuit;
- a latch circuit to latch each bit read from said memory circuit in synchronism with said clock;
- and
- a port output circuit to output each bit latched by said latch circuit to a corresponding port.
