CCS Technical Documentation System Module and User Interface Functional Description Modes of Operation AK4 baseband has six different functional modes: - No supply - Back-up - Acting Dead - Active - Sleep - Charging No Supply In NO_SUPPLY mode, the phone has no supply voltage. This mode is due to disconnection of main battery and backup battery or low battery voltage level in both of the batteries. Phone is exiting from NO_SUPPLY mode when sufficient battery voltage level is detected.
System Module and User Interface CCS Technical Documentation 13MHz-reference clock is generated in the UPP. VFLASH2 regulator is operating. In Active mode the RF regulators are controlled by SW writing into EM’s registers wanted settings: VR1A can be enabled or disabled. VR2 can be enabled or disabled and its output voltage can be programmed to be 2.78V or 3.3V. VR4 -VR7 can be enabled, disabled, or forced into low quiescent current mode. VR3 is always enabled in Active mode.
