WebRight Shift ( >> ): Right shift operator is a binary operator which shift the some number of bits, in the given bit pattern, to the right and append 1 at the end. Right shift is equivalent to dividing the bit pattern with 2k ( if we are shifting k bits ). 4 … WebSo, on Port A we have 5 pins, and hence 5 bits. If I wanted to set one of the pins to input, I send a ‘1’ to the relevant bit. If I wanted to set one of the pins to an output, I set the relevant bit to ‘0’. The bits are arranges in exactly the same way as the pins, in other words bit 0 is RA0, bit 1 is RA1, bit 2 is RA2 and so on.
