1.8V Minimum pulse is 200 μs
up to 900 msec. This
short pulse can cause an
unconditional radio
shutdown. There is no
controlled disconnect
from the network. The
radio restarts. The radio
takes 10 seconds to
recover and finish
starting.
Active Low: Properly
turn off and detach from
the carrier network. Low
for at least 1 second
turns off the 3G radio.
Shut off can take up to
30 seconds. High turns
on the 3G radio and it
needs at least 13
seconds before AT
commands are issued.
No connect if not used.
