Device Functions
3. Reading 30 bytes at R/W head 1, start address 10, problem during reading
Note
If a problem occurs after transmission of the data has started, the AF bit is provided
instead of the AE bit together with a corresponding status number. The AF status
message is dominant. Which data is incorrect cannot be specified. Setting the AF bit
cancels the job and declares it as finished.
