ECC Error Reporting Module

The Error Reporting Module (ERM) provides information and optional interrupt notification
on memory error events associated with ECC (Error Correction Code).
The ERM collects ECC events on memory accesses for local memory arrays, such as flash,
system RAM or peripheral RAMs.

ECC Error Injection Module

The Error Injection Module (EIM) provides support for inducing single-bit and multi-bit
inversions on read data when accessing peripheral RAM.
Table 33
The Error Injection on the Flash memory can be handled by reading the ECC/EDC test
pattern available in the UTEST memory.
