Document Type and Number:
Japanese Patent JP2885256
Kind Code:
B2
Abstract:
A microcomputer having a signal generating circuit which generates pulse width modulation signals defined by a carrier wave, and which controls controlled portions according to pulse width modulating signals. The signal generating circuit comprises a carrier wave defining timer which outputs a value varying the same as a waveform providing a carrier wave, a control register which controls the time period of the timer, a reload register which holds a count value, control blocks which generate pulse width modulation signals according to the value of the timer and the count value of the reload register.
