Software processing
Return to the main program
condition: 8bit-bus, CE0, SLC, 512 Bytes/Page, Hamming
The ECC generated for the read operation and the ECC read from the memory are
compared. If any error is found, the error processing routine is executed to correct the
error data. For details, see Section 3.11.4.2 “Error Correction Methods”.
