8.

Module: Reset

It has been observed that in certain Reset condi-

tions, including power-up, the first GOTO instruction

at address 0x0000 may not be executed. This

occurrence is rare and affects very few applications.

To determine if your system is affected, test a

statistically significant number of applications across

the operating temperature, voltage and frequency

ranges of the application. Affected systems will

repeatably fail normal testing. Systems not affected

will continue to not be affected over time.

Work around

Insert a NOP instruction at address 0x0000.
