Mode
NO_SUPPLY
(Dead) mode means that the main battery is not present or its voltage is too low (below
EM ASIC N2200 master reset threshold) and that the back-up battery voltage is too low.
BACK_UP
The main battery is not present or its voltage is too low, but back-up battery voltage
is adequate and the 32kHz oscillator is running (RTC is on).
PWR_OFF
In this mode (warm), the main battery is present and its voltage is over EM ASIC N2200
master threshold. All regulators are disabled, PurX is on low state, the RTC is on and
the oscillator is on. PWR_OFF (cold) is almost the same as PWR_OFF (warm), but the RTC
and the oscillator are off.
RESET
RESET mode is a synonym for start-up sequence. In this mode certain regulators are
enabled and after they and RFClk have stabilized, the system reset (PurX) is released
and PWR_ON mode entered. RESET mode uses 32kHz clock to count the REST mode delay
(typically 16ms).
SLEEP
SLEEP mode is entered only from PWR_ON mode with the aid of SW when the system
activity is low. There are in principle three different sleep modes:
• Application processor sleep
• RAPIDO sleep
• Application processor and RAPIDO sleep (deep sleep)
In sleep mode N2200's regulators VIO, VDRAM, VSIM1 and VANA are in low quiescent
current mode (output voltages still present but regulators will not give as much current
out). VSIM2 is permanently off, and VAUX is always in the power on mode. Other
regulators including VR1 supplying system clock oscillator are disabled.
In SLEEP mode, N2390 VCore SMPS regulator is in low quiescent current mode.
In SLEEP mode, N2300 EM ASIC linear regulator VOUT state depends on the accessory
connected to the AV connector, if there is any.
FLASHING
FLASHING mode is for SW downloading.
