Part 3.9: SD Card Slot

The AX7015 expansion board contains a Micro SD card interface to
provide user access to the SD card memory, the BOOT program for the ZYNQ
chip, the Linux operating system kernel, the file system and other user data
files.
The SDIO signal is connected to the IO signal of the PS BANK501 of ZYNQ.
Since the VCCMIO of the BANK is set to 1.8V, but the data level of the SD card is
3.3V, connected through the TXS02612 level shifter. The schematic of the
Zynq7000 PS and SD card connector is shown in Figure 3-9-1:
