Setting/Acquisition of Status of Power Control Function
This terminal has incorporated unique power control functions: the auto power OFF mode and
DOZE mode (CPU low-speed operation mode). Since these functions operate based on monitoring
a period free from operator's concern over a given interval, they have the potential of affecting the
execution performance of high-speed communication programs, including that of IrDA.
To create such a program call this function from it to disable the power control function.
If the power control function is set to disable, the monitoring of a period free from operator's
concern is ceased, resulting in auto-power off not taking place. Since the switch to the DOZE
mode does not occur either, the system can always be operable at high-speed. In short, this function
is useful if auto-power OFF does not take place during processing, or if enhancing the processing
speed.
