/*

* A macro for accessing FSL peripheral.

*

* This example driver writes all the data in the input arguments

* into the input FSL bus through blocking wrties. 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:

*        output_slot_id

*                Compile time constant indicating FSL slot from

*                which output data is read. Defined in

*                xparameters.h .

*        input_slot_id

*                Compile time constant indicating FSL slot into

*                which input data is written. Defined in

*                xparameters.h .

*        input_0    An array of unsigned integers. Array size is 1

*        output_0   An array of unsigned integers. Array size is 1

*

* 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 (fifo_link_app.c) for details.
