First determine whether the Output String (DECODE DATA STRING) is NOREAD (default).
• When using a Big (101) assembly;
There is a way to verify the External Output Status OUTPUT bit.
Please note that the External Output Status is dependent on the Output condition setting for the
Parallel I/O OUTPUT signal. The default setting is ON when there is a Read Fail.
• When an assembly after MXL/SLC (102) is selected;
You can verify the Read Cycle Pass, Read Cycle Fail bit status in Device Status. The Read
Cycle Pass, Read Cycle Fail bit is OFF during a READ cycle and is updated when Data Is Ready
is ON.
