The user can perform a hard reset of the SD card by using the processor reset line "NRST_OUT" signal (disabled by default) or the “NRST” reset system.

This action disables the MIC94085YFT power switch and forces VDD_SDCARD to ground. For more details about the MIC94085YFT power switch, refer to the product web page.
