* Function Name: SPIM_ReadStatus
********************************************************************************
*
* Summary:
* Read the status register for the component.
*
* Parameters:
* None.
*
* Return:
* Contents of the status register.
*
* Global variables:
* SPIM_swStatus - used to store in software status register,
* modified every function call - resets to zero.
*
* Theory:
* Allows the user and the API to read the status register for error detection
* and flow control.
*
* Side Effects:
* Clear status register of the component.
*
* Reentrant:
* No.
