1.55 µs (when two inputs are used) + 0.60 µs (for every additional input). When all
inputs are used, the execution time is 19.55 µs.
The output (OUT) is 0, if all connected inputs (IN) are 0. Otherwise the output is 1.
Truth table:
IN1 IN2 OUT
0 0 0
0 1 1
1 0 1
1 1 1
The inputs can be inverted.
The number of inputs (2...32) is selected by the user.
Input (IN1...IN32): Boolean
Output (OUT): Boolean
1.28 µs
Input bits (I) are rotated to the left by the number (N) of bits defined by BITCNT. The N
most significant bits (MSB) of the input are stored as the N least significant bits (LSB) of
the output.
Example: If BITCNT = 3
3 MSB
