Output Flags Word n+9
The number of each bit in IR word n+9 corresponds to an output number. An out-
put flag is ON whenever the specified output is ON. Output flags are turned ON
regardless of the status of ENABLE OUTPUT.
4-2-4 Timing Chart
The following chart shows timing relationships between the command bits (input
bits) and output bits in linear and circular mode.

a: Normal outputs

1, 2, 3... 1. START is effective on the rising edge.
2. External outputs are prohibited when ENABLE OUTPUT is OFF.
3. The Counter Units stops counting on the falling edge of START. Status
of internal and external outputs are retained.
4. The status of the output force bits is output when ENABLE FORCED
OUTPUT is ON. All outputs are reset when ENABLE FORCED OUT-
PUT goes OFF.
5. Setting START during counting returns all outputs to normal status, i.e.,
makes ENABLE FORCED OUTPUT ineffective. The status of output
force bits is then restored when STOP goes OFF.
6. ENABLE FORCED OUTPUT is ineffective while START is ON.
