6.89 SYS5

SYS Module

Function

Higher priority NMI interrupt lost during execution of lower priority NMI ISR

Description

If a higher prioritized NMI occurs during the execution of a lower priority NMI ISR (read out of NMI vector word) the higher IFG can get lost (but lower interrupt is executed), which leads to a second execution of the lower NMI. The bug only occurs if the NMIs are of the same type (UNMI or SMNI).

Workaround

None.
