5. STANDBY FUNCTIONS
The µPD78362A is provided with standby functions to reduce the power consumption of the system. The
standby functions can be effected in the following two modes:
• HALT mode ..... In this mode, the operating clock of the CPU is stopped. By using this mode in
combination with an ordinary operation mode, the µPD78362A operates
intermittently to reduce the total power consumption of the system.
• STOP mode .... In this mode, the oscillator is stopped, and therefore the entire system is stopped.
Therefore, power consumption can be minimized with only a leakage current
flowing.
Each mode is set through software. Figure 5-1 shows the transition of the status in the standby modes (STOP
and HALT modes).
