Power saving circuit
Fig. 3.2-10 shows a circuit diagram of the power saving circuit. If you power off the machine with
the power On/Off key or you make no key entry for approx. 5 minutes, the CPU turns P11 high to
cut off the Vcc (which normally would feed power to the logic circuits except the CPU). In this
way, the CPU enters the sleep mode where oscillation stops so as to feed no clock to the CPU.
In the sleep mode, the +5BV feeds power only to the CPU.
To cancel the power saving mode (automatic powering-off mode) and resume the normal
operation mode, press the power On/Off key.
