Question:

XINTF is not working on my 2833x.  What could be the problem?

Answer:

Please check the following:

  • There is an errata against the XINTF that will keep it from functioning after a power-on reset.  Please refer to the errata for the workaround.
  • Correct configuration of the XINTF pins - these are shared with other I/O functions and must be configured for XINTF use. 
  • Make sure the XINTF clock is enabled.
  • Check the output signals - are any of them being asserted?  Are all of them connected properly to the external device?  If the device is in a socket is it securely seated?
  • Check that XHOLD is not tied low on the board.
