3.5. Turn off

3.5.1. Turn off the Module through FCPO#

For the design that turns on the module with a host GPIO, when the power is supplied to VCC, driving
FULL_CARD_POWER_OFF# pin LOW (≤ 0.2 V) or tri-stating the pin will turn off the module.
The timing sequence of turning-off scenario is illustrated by the following figure.
