4. Power Up With RTC
Each of four methods is described in general in the following sections. When the battery
is connected to phone, nothing will happen until the power–up procedure is initiated; for
instance, by pressing the power button or by connecting a charger. After that the 32kHz
crystal oscillator of CCONT is started (can take up to 1 sec), and the default regulators
are powered up.
If a power down is done and the battery remains connected, the 32 kHz crystal oscillator
keeps running in the CCONT.
