Power On
To turn on the ML865G1 the pad ON_OFF/WAKE must be set HIGH level for at 5 seconds
and then released.
ON_OFF/WAKE pad can make also 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 HIGH level for 5 seconds.
The signal ON_OFF/WAKE can be directly connected to any GPIO (1.8V) of Application
Processor with a totem pole output. A level shifter is not required.
The typical current consumption of the input ON_OFF/WAKE pad is 0.25mA@1.8V.
NOTE:
Don't use any pull down resistor on the ON_OFF/WAKE line, it is
internally pulled down.
The VAUX/PWRMON pin can be monitored by application processor
to check if the device is powered ON.
