Webintout = bitset (A,bit) returns the value of A with position bit set to 1 (on). intout = bitset (A,bit,assumedtype) assumes A is of type assumedtype. intout = bitset (A,bit,V) returns … Web6 Answers. Sorted by: 10. Assuming value is 0 or 1: REG = (REG & ~ (1 << pin)) (value << pin); I use REG instead of register because as @KerrekSB pointed out in OP comments, register is a C keyword. The idea here is we compute a value of REG with the specified bit cleared and then depending on value we set the bit.
