Power Control (Pin 35)

The input is equivalent to the "phone ON-button". A falling-edge on this Active-Low input will switch-ON
the module or switch-OFF the module after a delay. This input has a "weak pull-up" resistor internal to
the module. This input can be left grounded if the "RTC Sleep Function" is not required. If RTC Sleep is
required, see Section 6.6.10.

6.6.10. RTC Sleep

In this mode, the modem is off except for its Real-Time-Clock. When put into this mode, the modem
can wake itself up at a designated time/interval.
