RESET CIRCUIT:
CLOCK CIRCUIT:
PIC-GSM reset circuit is made with RC group and optional STM1001R chip
with typical threshold +2.63V. By default STM1001R chip is not assembled
Quartz crystal 25MHz is connected to PIC18F97J60.

jumper 4V_VBAT must be open
jumper 5V_CHG_E must be closed
Power consumption in this mode: depend on the battery charge
may vary between 90mA and 300mA.
If the 12V power supply is missing the battery discharge current
depend from activated microcontroler modules. Max current
consumption reach up to 500 mA when all microcontroler moduls
are switched on and have a conversation.
