Internal operation modes
A simplified flow chart of the internal operation modes of TME-3 below.
Figure 4: Internal operation modes
In NO_SUPPLY mode the phone has no supply voltage.
When battery voltage appears, TME-3 enters RESET mode. In TME-3, RESET mode leads
always to POWER_ON mode. During low activity TME-3 can switch from POWER_ON to
SLEEP mode. PROTECTION mode happens if the thermal shutdown of UEM regulators
triggers. PROTECTION mode leads immediately to POWER_OFF mode. TME-3 can enter
POWER_OFF mode also from POWER_ON or SLEEP modes if the UEM internal watchdog
elapses. POWER_OFF mode is not stationary.
In TME-3 there is a special power-up hardware, which essentially presses automatically
the power key as soon as it detects the POWER_OFF mode.
