Driver functions will return a status code when they are called to perform
a certain task for the application. When a function returns a code that is
not zero, it means the function has failed to perform its designated func-
tion. To troubleshoot the Device Drivers error, you can pass the error
code to DRV_GetErrorMessage function to return the error message.
Alternatively, you can refer to the Device Drivers Error Codes Appendix
in the Device Drivers Manual for a detailed listing of Error Codes, Error
IDs and the Error Messages.
