MSC_Setup
Description
This function used to setup the Msc and Ctrl handles. This is an internal function and is called from MSC_Open or MSC_OpenFullspeed functions.
Arguments
pAppClassHandle Application handle to the MSC Class Obj
usbSpeedCfg USB speed selection parameter
0 - USB MSC operates in fullspeed mode
1 - USB MSC operates in highspeed mode
Return Value CSL_Status
Pre Condition
None
Post Condition
Initializes Msc and Ctrl handles
Modifies
Msc and Ctrl handle data
Example
CSL_MscInitStructApp mscAppHandle;
pMscAppClassHandle pAppClassHandle;
Uint16 mscAppBuffer[420];
CSL_Status status;
pAppClassHandle = &mscAppHandle;
// Assign values to all the members in mscAppHandle struct
mscAppHandle.pMscObj = &mscAppBuffer[0];
.....
.....
// Setup USB for highspeed
status = MSC_Setup(pAppClassHandle, TRUE);
