SD Card Interface

[Figure
1-2, callout 5]
The KC705 board includes a secure digital input/output (SDIO) interface to provide
user-logic access to general purpose nonvolatile SDIO memory cards and peripherals. The
SD card slot is designed to support 50 MHz high speed SD cards.
The SDIO signals are connected to I/O bank 12 which has its VCCO set to VADJ. A Texas
Instruments I TXB0108 8-bit bidirectional voltage-level translator is used between the FPGA
