Memory: Possible Incorrect Operation of XINTF Module After Power Up

Dear,

  This file TMS320F2833x and TMS320F2823x DSC Silicon Errata  has the following description:

Revision(s) Affected 0, A


Details    

                  The XINTF module may not get reset properly upon power up. When this happens,
                   accesses to XINTF addresses may cause the CPU to hang. This issue occurs only upon
                    power up. It does not happen for other resets such as a reset initiated by the watchdog
                   or an external (warm) reset using the XRS pin.
Workaround(s)

                 After coming out of reset, software should force a watchdog (WD) reset if WDFLAG = 0
                 in the WDCR register. WDFLAG = 0 implies that an external reset occurred, for example,
                  a power-on reset. After exiting the WD reset, WDFLAG will be 1. In this case, software
                 should clear the WDFLAG bit before continuing normal code execution. This issue
                 affects only the XINTF module

I encountered this problem, what should I add the code to avoid this problem.

Can you give me a specific code?
