INTSM – Integer number bit shift and mask

Block SymbolLicensing group: STANDARD
PIC

Function Description
The INTSM block performs bit shift of input value i by shift bits right (if shift is positive) or left (if shift is negative). Free space resulting from shifting is filled with zeros.

Output value n is calculated as bitwise AND of shifted input i and bit mask mask.

Typical application of this block is extraction of one or more adjacent bits from a given position in integer register which was read from some external system.
