If you mean combining bits to make a WORD value - its just basic math functionality of the programming language. e.g.... //Get bit function getBit(number, bitPosition) { return (number & (1 << bitPosition)) === 0 ? 0 : 1; } //Set Bit function setBit(number, bitPosition) { return number | (1 << bitPosition); } //Clear Bit function clearBit(number, bitPosition) { const mask = ~(1 << bitPosition); return number & mask; } //Update Bit function updateBit(number, bitPosition, bitValue) { …
