Revision(s) Affected:

AWR1443 ES1.0, AWR1443 ES2.0, and AWR1443 ES3.0

Description:

If a system reset (nRST goes low) occurs while the debugger is performing an access on the system resource using system view, a slave error should be replied to the debugger. If the access was a read, instead the response might indicate that the access completed successfully and return unpredictable data.

This issue occurs under this condition: when a system reset is asserted (nRST low) on a specific cycle, while the debugger is completing an access on the system, using the system view. An example would be, when a debugger, like the CCS-IDE memory browser window, is refreshing content using the system view. This is not an issue for a CPU only reset and, this is not an issue during a power-on-reset (nPORRST) either.

Workaround(s):

Avoid performing debug reads and writes while the device might be in reset.
