5. Hardware Commands
5.1. Turning ON the GE864-QUAD V2
To turn ON the GE864-QUAD V2 the pad ON# must be tied low for
at least 1 second and then released.
When the power supply voltage is lower than 3.4V the pad ON#
must be tied low for at least 4 seconds.
The maximum current that can be drained from the ON# pad is
0,1 mA.
A simple circuit to do it is:
NOTE:
Don't use any pull up resistor on the ON# line, it is
internally pulled up. Using pull up resistor may bring to
latch up problems on the module, power regulator and improper
power on/off of the module. The line ON# must be connected
only in open collector configuration.
NOTE:
In this document all the lines that are inverted, hence have
active low signals are labeled with a name that ends with a
"#".
TIP:
To check if the device has powered on, the hardware line
PWRMON should be monitored. After 1000ms the line raised up
the device could be considered powered on
