9.2.9 Command 0x09 - Deep Sleep
The Deep Sleep command will put the XDM2140 into a non-functional, lowest-power consumption state
with current draw on the order of a few microamps. Deep sleep is ideal when the XDM2140 is connected
to its power source, but must be stored for extended periods. The XDM2140 will enter deep sleep within
2 seconds after receiving the Deep Sleep command. The XDM2140 will wake from deep sleep when
either the /RESET IN pin is asserted and then de-asserted, or the XDM2140 is power cycled.
