Issue : Example given for TMS570LC43xx in HALCOGEN for mibspi is not working
Doing all the configuration as per given in the sample example file.
/** @example example_mibspi_loopback.c
* This is an example which descibes the steps to create Mibspi Loopback check
*
* @b Step @b 1:
*
* Create a new project.
*
* Navigate: -> File -> New -> Project
*
* @image html example_createProject.jpg "Figure: Create a new Project"
*
* @b Step @b 2:
*
* Configure driver code generation:
* - Enable MIBSPI 1 to 5 driver
* - Disable others
*
* Navigate: -> TMS570Sxx /RMxx -> Enable Drivers
*
* @b Step @b 3:
*
* Enable Interrupts
* - Enable all MIBSPI interrupts in the MIBSPI VIM Channels tab.
*
* @b Step @b 4:
*
* Configure MIBSPI
* - Leave the Transfer group configuration as default
*
* @image html example_mibspi_config.jpg "Figure: Configure MIBSPI"
* @b Step @b 5:
*
* Generate code
*
* Navigate: -> File -> Generate Code
*
* @image html generateCode.jpg "Figure: Generate Code"
*
* @b Step @b 6:
*
* Copy the source code below into your sys_main.c (or) replace sys_main.c with this file.
*
* The example file example_mibspi_loopback.c can also be found in the examples folder: ../HALCoGen/examples
*
* @note HALCoGen generates an empty main function in sys_main.c.
