5.8 DDC Instructions
5.8.1 Dead Zone A (DZA)
( 1 ) Operation
The DZA instruction calculates the output value by comparing the input value against a predefined dead zone.
As shown in the following figure, if the absolute value of the input value is greater than or equal to the absolute value
of D, the input value is outside of the dead zone, so it becomes the output value.
If the absolute value of the input value is less than the absolute value of D, the input value is inside of the dead zone, so
the output is set to 0.
