R5FSS: Errors in ECC injection logic are not detected because
the pending interrupts are tied low
The device has the ability to intentionally introduce ECC errors on memory reads to test that the ECC checking logic is working (a test-for-diagnostic). The logic also contains the ability to detect faults in this injection logic (latent faults). However, there is an issue that causes these errors not to be reported. The result is a slight reduction in latent fault coverage reflected in all FMEDA calculations. The diagnostic (ECC) and the ability to test the diagnostic are not affected.
None.
