COMX-P4080-2G-ENP2 Installation and Use (6806800P63B)

45

After reset, the direction for all GPIOs are set to input. So all the GPIOs used as output needs to
be reconfigured.

4.12 SDHC

COMX-P4080-2G-ENP2 provides an SD/MMC interface to the COM Express connector and
there should be a SD card connector provided on the carrier.
