Function

Flash content may degrade due to aborted page erases

Description

If a page erase is aborted by EEIEX, the flash page containing the last instruction before erase operation will start to degrade. This effect is incremental and, after repetitions, may lead to corrupted flash content.

Workaround

- Use the EEI (interrupted erasing) feature instead of EEIEX (abort erasing).
or
- A PSA checksum can be calculated over affected flash page using the marginal read mode (marginal 0). If PSA sum differs from expected PSA value the affected flash page has to be reprogrammed.
or
- Start flash erasing from RAM and limit system frequency to <1MHz (to ensure 6-us delay after EEIEX).  If the last instruction before erasing is located in RAM, flash cell degradation does not occur.
