Description
SDIO Card Detect. This signal indicates when a SDIO/MMC card is
present.
SDIO Clock. With each cycle of this signal a one-bit transfer on the
command and each data line occurs. This signal has maximum
frequency of 48 MHz.
SDIO Command/Response. This signal is used for card initialization and
for command transfers. During initialization mode this signal is open
drain. During command transfer this signal is in push-pull mode.
SDIO Write Protect. This signal denotes the state of the write-protect tab
on SD cards.
SDIO Power Enable. This signal is used to enable the power being
supplied to a SD/MMC card device.
SDIO Data lines. These signals operate in push-pull mode
