WebThe ECC logic implemented in the S32K1xx Flash memory can correct single-bit fault automatically and can detect multiple-bit fault in each NVM sections. The multiple-bit fault is enabled using the FERCNFG[DFDIE] bit. WebECC is disabled automatically if multiple programming operations are done on the same ECC unit. Single-byte programming or bit walking is allowed in certain flash device options, but it disables ECC on the second program to the same 16-byte ECC unit. To re-enable ECC for an ECC unit that has been disabled, the sector that includes the ECC unit
