<h2>Mutual exclusive access support for RTOS</h2>
|

<p>MMCCARD driver has added mutual exclusive access support for init/deinit/write/read/erase function. Please note that the card init function will create the mutex lock dynamically by default, so to avoid the mutex create redundantly, application must follow bellow sequence for card re-initialization. </p>

<p>A Flush operation refers to the requirement, from the host to the device, to write the cached data to the nonvolatile memory. Prior to a flush, the device may autonomously write data to the nonvolatile memory, but after the flush operation all data in the volatile area must be written to nonvolatile memory. There is no requirement for flush due to switching between the partitions. (Note: This also implies that the cache data shall not be lost when switching between partitions). Cached data may be lost in SLEEP state, so host should flush the cache before placing the device into SLEEP state.</p>
