Only one sub page of 512 bytes is corrected at a time. If several sub page are on error then it is necessary to do several time
the correction process.
This bit is set to one when a multiple error have been detected by the ECC-RS.
This bit is cleared when a read/write command is detected or a software reset is performed.
1: Multiple errors detected: more than four errors.Registers for one ECC for a page of 512/1024/2048/4096 bytes
0: No multiple error detected
