3.4.1.2. Turn on the Module Automatically
If FULL_CARD_POWER_OFF# is pulled up to VCC with a 5–10 kΩ resistor, the module will be powered
on automatically when the power supply for VCC is applied.
A reference circuit is shown in the following figure.
Host Module
FULL_CARD_POWER_OFF#
GPIO
VCC_IO_HOST
Notes:
1. The voltage of pin 6 should be no less than 1.19 V when it is at HIGH level.
2. The voltage level VCC_IO_HOST could be a 1.8 V or 3.3 V typically.
