Regarding EEPROM 2 bit ECC Machine exception

[pratibhasurabhi]

The EEPROM Flash 2 bit fault will generate a machine exception.

Will this case hold true if we "simulate" the double bit fault by setting the FDFD bit.

[RadekS]

Hi Pratibha,

no, forcing the DFDF status bit by setting FDFD (see Section 20.3.2.5) has effect only on the DFDF status bit value and does not result in an invalid access.

SeeS12Z - Simulating ECC errors at EEPROM by cumulative write example code for more details regarding simulating machine exception due to double bit ECC error.

I hope it help you

Have a great day,
Radek
