Execution Status
Note:
Once the automatic algorithm has been started, read access to the specified address is
ignored. Data reading is allowed after the data polling flag (DQ7) is set to "1". Data
reading after the end of the automatic algorithm should be performed following read
access made to confirm the completion of data polling.
