It is recommended to use a host GPIO to control FULL_CARD_POWER_OFF#. A simple reference circuit
is illustrated by the following figure.

NOTE:
The voltage of pin 6 should be no less than 1.19 V when it is at high level.
The timing sequence of turn-on scenario is illustrated by the following figure.
