Remark:
1.
When this function is specified (ARRE = "1"), the EER flag's specification in the
MODE SELECT parameter is made invalid and Read retry processing is performed
up to the number of times specified in the "Number of Retries during Read"
parameter. If "0" is specified in the DCR flag, correction processing of the data is
performed afterward (see item 4.3.1 (4)). When "1" is specified in the DCR flag,
ECC correction processing is prohibited, so even if "1" is specified in the ARRE flag,
auto alternate block allocation processing will not be executed for errors in the data
area.
2.
When errors in the data area are recovered from by ECC correction processing, before
implementing alternate block allocation processing, rewriting of the recovered data
and a verify check (rereading) are performed. If data are recovered by rewriting,
alternate block allocation of that data block is not performed.
3.
Auto alternate block allocation processing is executed even if a write operation is
prohibited by the SET LIMITS command. However, when a write operation is
prohibited through the setting terminal, the auto alternate block allocation processing
specification is disabled.
