Title: One chip microcomputer
Inventor: NOSE TADASHI
IPC: G06F21/12
Filed: 1981-11-30
Abstract: PURPOSE:To protect the software stored internally, by providing a readout control memory in a microcomputer, writing a readout inhibiting signal after debugging, and inhibiting the output operation of a bidirectional bus control circuit with the output of readout control memory. CONSTITUTION:After data are written and verified in an ROM2 of a microcomputer 1, readout is inhibited externally to the data of the ROM2. In supplying a pulse overvoltage signal of ''H'' to an input terminal I1 and writing ''H'' to a specific bit of a readout control memory 7, this output is normally ''H'' and the output of an OR gate 8 keeps ''H'' to be outputted at all times independently of the readout signal applied to an input terminal I2. Thus, the data output operation of a bidirectional bus control circuit 6 is inhibited. Then, the readout of the software data written in the ROM can be prevented and the software is protected.

Abstract: PROBLEM TO BE SOLVED: To restrict the rise in the rotating speed of a motor caused by a trouble in a rotation detecting section, by reducing an angle of ON period of semiconductor control means through phase control means when the output voltage of an FV conversion means is smaller than the predetermined value. SOLUTION: A rotating speed of a motor 3 is detected by rotation detecting means 6, a DC voltage made proportional to the rotating speed of the motor 3 by an FV conversion means 7 is compared to a set voltage of the rotating speed setting means 8 by differential amplifier means 9, phase control means 10 is controlled by a phase control voltage outputting from operational amplifier means 9, and the rotation of the motor 3 is controlled to a constant value. That is, if a load to the motor 3 increases and the rotating speed of the motor decreases, then the output voltage of FV conversion means 7 decreases, and the phase control voltage of the differential amplifier means 9 increases. Then, the angle of ON period of semiconductor control means 4 of the phase control means 10 is made larger, and the rotating speed of the motor is increased.  On the contrary, if the load rises and the rotating speed of the motor increases, then the angle of ON period of the semiconductor control means 4 is reduced and the rotating speed of the motor is decreased.
