Explanation of function and operation

1. 16-bit operation (INCD)

The current value

of a counter is compared with the data table having "n" lines starting from

(which

occupies "n" lines x 1 device). When

is equivalent to the table data, the current output is reset, and the next

output is set to ON. In this way, the ON/OFF status of specified outputs is controlled in turn.
