/*
* A macro for accessing FSL peripheral.
*
* This example driver writes all the data in the input arguments
* into the input FSL bus through blocking writes. FSL peripheral will
* automatically read from the FSL bus. Once all the inputs
* have been written, the output from the FSL peripheral is read
* into output arguments through blocking reads.
*
* Arguments:
*	 input_slot_id
*		 Compile time constant indicating FSL slot from
*		 which coprocessor read the input data. Defined in
*		 xparameters.h .
*	 output_slot_id
*		 Compile time constant indicating FSL slot into
*		 which the coprocessor write output data. Defined in
*		 xparameters.h .
*	 input_0    An array of unsigned integers. Array size is 8
*	 output_0   An array of unsigned integers. Array size is 8
*
* Caveats:
*    The output_slot_id and input_slot_id arguments must be
*    constants available at compile time. Do not pass
*    variables for these arguments.
*
*    Since this is a macro, using it too many times will
*    increase the size of your application. In such cases,
*    or when this macro is too simplistic for your
*    application you may want to create your own instance
*    specific driver function (not a macro) using the 
*    macros defined in this file and the slot
*    identifiers defined in xparameters.h .  Please see the
*    example code (fsl_dct_app.c) for details.
