您好,请问DM3730的mmc1接口能够连接采用SDIO接口的WIFI芯片么?
DM37xx的数据手册有这样的描述 :
The first controller (MMC/SD/SDIO1) integrates an internal transceiver that allows a direct connection to the MMC/SD/SDIO card (1.8 and 3V), without external transceiver. It supports 1-bit and 4-bit data transfer modes.
• The second controller (MMC/SD/SDIO2) allows connecting MMC/SD/SDIO cards (only 1.8V cards) or an external device that uses the MMC/SD/SDIO interface (WLAN device for example). The second instance also supports an external transceiver and provides direction signals for data and command. It supports 1-bit, 4-bit and 8-bit data transfer modes. Using an external transceiver device precludes 8-bit transfer mode.
谢谢!
