Function

Prefetcher can cause data integrity issues when transitioning into SLEEP mode

Description

When transitioning into SLEEP0 the prefetcher can erroneously fetch incorrect data (all 0's). When coming out of sleep mode, if the prefetcher and cache do not get overwritten by ISR code, then the main code execution from flash can get corrupted. For example, if the ISR is in the SRAM, then the incorrect data that was prefetched from Flash does not get overwritten. When the ISR returns the corrupted data in the prefetcher can be fetched by the CPU resulting in incorrect instructions.

Workaround

Disable prefetcher before entering SLEEP.
