2.7.6 CPU Power State Control
The following shows the power states operable on the terminal.
Table 2.79
State Contents
Discharge State in that the battery pack and the super capacity have been discharged.
Neither content in the RAM nor the RTC is backed up.
RTC backup State in that only the RTC is being backed up. The content in the RAM is not
backed up.
SLEEP mode State in that the power on the terminal is turned off, and peripheral devices
are also turned off. The RTC and the content in the RAM are backed up.
RUN mode State in that the terminal is running or application is running on the terminal.
POWERSAVE The CPU is running at 208 MHz.
NORMAL The CPU is running at 312 MHz.
TURBO The CPU is running at 628 MHz.
AUTO The CPU is running at either 104, 208, 312, 624, or 60 MHz depending on
the CPU load.
IDLE mode State in that the terminal or application is waiting for an event to occur.
DeepIdle If the CPU clock frequency has been set to “AUTO” mode, and the backlight
is turned off, the CPU runs at 13MHz (“DeepIdle” mode).
Note however that the CPU will be in ordinary “Idle” state, not DeepIdle
mode, if periodical accesses are made to the integrated WLAN module.
