If the programming failure quantity is within the range of values provided
in, Table 1-1 through Table 1-5, open a technical support case at
www.microchip.com/support.
For fallout with quantities greater than those listed in, Table 1-1 through Table 1-5, a case must be initiated with Technical Support to
investigate the issue further.
- 1.Open a case through Customer Portal -
www.microchip.com/support.
- 2.Attach the completed FA checklist (fill in the “Programming” tab) in the case
opened through Customer Portal.
- 3.Attach the programming log file in the
case opened through the Customer Portal.
