Power On
To turn on the ME910C1 the pad ON_OFF*/WAKE* must be tied low for at least 6 second
and then released.
The maximum current that can be drained from the ON_OFF*/WAKE* pad is 0,1 mA.
ON_OFF*/WAKE* pad can make an asynchronous wakeup of the system from the PSM
Mode, before the scheduled event of timer T3412 expired.
To make asynchronous exit from PSM mode ON_OFF*/WAKE* pin must be set LOW for at
least 6 seconds.
Figure 1 illustrates a simple circuit to power on the module using an inverted buffer output.
