Operation The block compares bits of three 24 bit word inputs and forms the output bits as
follows:
O = (I1 OR I2) AND I3
Example
Connections Input I1: 24 bit integer value (packed boolean)
Input I2: 24 bit integer value (packed boolean)
Input I3: 24 bit integer value (packed boolean)
Output (O): 24 bit integer value (packed boolean)
