5.8.2 Dead Zone B (DZB)
( 1 ) Operation
The DZB 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 less than the absolute value of D, the input
value is inside of the dead zone, so the output is set to 0.
Unlike the DZA instruction, when the input value is outside of the dead zone, the sign of the input value determines
whether the output value is obtained by adding the absolute value of D to or subtracting it from the input value.
( 2 ) Format
∗ C and # registers cannot be used.
Dead zone set value = D
0
+ | D |
- | D |
If | Input value | < | D |
Output value = 0
If Input value < 0 and | Input value | ≥ | D |
Output value = Input value + | D |
If Input value > 0 and | Input value | ≥ | D |
Output value = Input value – | D |
