4.1 Mode Parameters
C141-E167 4 - 3
• READ • WRITE
• READ EXTENDED • WRITE AND VERIFY (Write operation)
• READ LONG • WRITE EXTENDED
• SEND DIAGNOSTIC (Write/read test) • WRITE LONG
a. AWRE (automatic write reallocation enabled)
"1" : An "automatic alternate block allocation processing" operation is specified during
execution of a write operation.
"0" : An "automatic alternate block allocation processing" operation is prohibited during
execution of a write operation.
Automatic alternate block allocation processing is explained in Section 5.3.2.
b. ARRE (automatic read reallocation enable)
"1" : An "automatic alternate block allocation processing" operation is specified during
execution of a read operation.
"0" : An "automatic alternate block allocation processing" operation is prohibited during
execution of a read operation.
Automatic alternate block allocation processing is explained in Section 5.3.2.
c. TB (transfer block)
"1" : Data blocks which contain errors that are impossible to correct are transferred to the INIT
during a read operation.
"0" : Data blocks which contain errors that are impossible to correct are not transferred to the
INIT during a read operation.
d. RC (read continuous)
This bit specifies continuous transfer of all the data requested by a command unaccompanied by
a delay for executing error recovery processing.
e. EER (enable early recovery)
"1" : When a correctable data check has been detected, data correction according to the ECC is
applied immediately without executing retry (rereading) up to the number of times
specified in the "Number of retries during READ" parameter.
"0" : When a correctable data check has been detected, retry (rereading) is executed up to the
number of times specified in the "Number of retries during READ" parameter, then data
correction according to the ECC is applied if possible.
The IDD disregards this bit and operates according to the default value (=1).
