Baseband Module

The baseband architecture supports a power saving function called sleep mode. This sleep mode shuts off the VCTCXO, which is used as system clock source for both RF and baseband. During the sleep mode the system runs from a 32 kHz crystal. The phone is waken up by a timer running from this 32 kHz clock supply. The sleeping time is determined by some network parameters. The sleep mode is entered when both the MCU and the DSP are in standby mode and the normal VCTCXO clock has been switched off....

1 Power switch pressed > Digital voltages on in CCONT (VBB) 2 CCONT digital reset released. VCXO turned on 3 62 ms delay to see if power switch is still pressed. IBI can power CCONT up by giving a short pulse (10ms) through the BTEMP line. After power-up BTEMP will act as any other input channel for ADC. When the PURX reset is released, the MAD releases the system reset ExtSysResetX and the internal MCUResetX signals and starts the boot program execution from MAD bootrom if MAD GenSDIO pin is...

Alt, S,l Open Phone Identity dialog box for editing Function is used to edit phone identity. NOTE product code cannot be changed with this dialog, if product code is invalid, e.g. after EEPROM change, change product code first with Production Data Edit. With this dialog IMEI or SIM locks may be changed in following manner - current phone information is read from phone - user edits User Name and IMEI and Product Code, if they were not read correctly from phone. But ifyou have to change product...
