Reading Data with the READ DATA Bit Section 5-3
After the data reading operation has been completed, the Data Transferring
Flag (word n+8, bit 14) is turned from ON to OFF. If an error occurs during
data transfer, the Error Flag (word n+8, bit 12) will be turned ON and the error
code will be output to n+10 in the operating memory area. Check this error
code to determine the cause of the error and correct it.
