BZAND: Dead zone control
◆
Overview
The BZAND instruction controls an output value based on whether the input value is within the range (dened
by upper and lower limits) of the designated dead zone.

Function
1) 16-bit instruction
A dead zone range is set in [S1] and [S2] and applied to the input value in [S3]. The resulting value is
output to the element [D].
The output value is controlled as follows:
[S3] – [S1] -> [D] when [S1] > [S3];
[S3] – [S2] -> [D] when [S2] < [S3];
0 -> [D] when [S1] ≤ [S3] ≤ [S2].
