SYNC mode:
Enables the SYNC pin to indicate growing power consumption during a trans-
mit burst. You can make use of the signal generated by the SYNC pin, if power
consumption is your concern. To do so, ensure that your application is capable
of processing the signal. Your platform design must be such that the incoming
signal causes other components to draw less current. In short, this allows your
application to accommodate current drain and thus, supply sufficient current to
the GSM engine if required.
Note: =0 is the factory default of the TC35i module. In the case of the

TC35i Terminal this mode is not applicable and should not be selected.
