Explanation of function and operation
1. 16-bit operation (ABSD)
In this example, outputs are controlled to ON or OFF by one rotation (0 to 360
° using the rotation angle signal of 
1
°/pulse).
The current value 
 of the counter is compared with the data table with "n" lines starting from 
 (which
occupies "n" lines 
× 2 devices), and consecutive "n" outputs starting from 
 are controlled to ON or OFF during
one rotation.
