AM2632: How to configure MMCSD DATA1 interrupt

Part Number: AM2632

Tool/software:

Hi Expert 

Customer need to configure the MMCSD DATA1 interrupt the background is below:

The AM2632 is used in projection as host MCU. Customer want to use interrupt mode instead of polling mode. When the WiFi module is connected as SDIO, the module needs to notify the MCU to obtain the data after receiving the data. At this time, the module will pull down the DATA1 pin of SDIO. When the MCU detects that the pin is low, it will send a interrupt to obtain the data.

Thanks

Joe
