Flash ECC error injection in MPC5744P

We are injecting ECC errors in Flash according to example "MPC5744P_1b+2b_FLASH_ECC_error_by_UTEST_area_read-v0_0-GHS614".


For FCCU NCF[22] "Flash uncorrectable ECC error" we have configured reaction to 'long reset. For FCCU NCF[21] "Flash correctable ECC error" we have configured reaction to 'no reaction'. But, we can although observe that there is a MCU reset performed when triggering the "Flash correctable ECC error". What can be the cuse of this reset?


The last comment in example function Inject_1bit_FLASH_ECC_error_by_UTEST_read() is

// ECC is checked and non-correctable error found

But, it should be

// ECC is checked and correctable error found
