/*
* 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.
