Splet06. maj 2024 · PORTC = (PORTC & 0xf0) ( (row >> 6) & 0x0f); Let’s say, for example: PORTC is B10111011 and that row is B11010011. (PORTC & 0xf0) is B10111011 & B11110000. Which reduces to B10110000. In other words, the 4 lower order bits of PORTC are masked out. (row >> 6) is B11010011 shifted right 6 places, that is B00000011.
