Info

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. RTC ( internal in CCONT) can power the phone up by changing RTCPwr to logical 1. RTCPwr is an internal signal from the CCONT digital section. IBI can power CCONT up by sending a short pulse to logical 1. RTCPwr is an internal signal from the CCONT digital section. If the phone is off when the charger is connected, the phone is...

Cobbagj

Requirements for a real time clock implementation are a basic clock (hours and minutes), a calender and a timer with alarm and power on off -function and miscellaneous calls. The RTC will contain only the time base and the alarm timer but all other functions will be implemented with the MCU software. The RTC needs a power backup to keep the clock running when the phone battery is disconnected. The backup power is supplied from a rechargable polyacene battery that can keep the clock running some...

Baseband Testing

The MCU software enters a local mode at start-up if suitable resistors are connected to the BTEMP and BSI lines. NOTE Baseband doesn't wake up automatically when the battery voltage is connected. Power must be switched on via In the local mode the baseband can be controlled through MBUS or FBUS connections by a PC-locals software. Baseband internal connections are tested with self tests if possible. By connecting MAD2 pin ROW5 to ground, MAD2 pins are toggled as a daisy chain, which can be used...
