The CC3220MODx and CC3220MODAx modules provide an interface between a local host (LH), such as an MCU and an SD memory card, and handles SD transactions with minimal LH intervention.
The SD host does the following:
The application interface sends every SD command and either polls for the status of the adapter or waits for an interrupt request. The result is then sent back to the application interface in case of exceptions or to warn of end-of-operation. The controller can be configured to generate DMA requests and work with minimum CPU intervention. Given the nature of integration of this peripheral on the CC3220x platform, TI recommends that developers use peripheral library APIs to control and operate the block. This section emphasizes understanding the SD host APIs provided in the peripheral library of the CC3220x Software Development Kit (SDK).
The SD Host features are as follows:
