WebJul 27, 2014 · Since device registers usually contain fields of one or more bits, each of which corresponds to specific functionality (as shown in the example above), it would seem logical to use bit fields in a C structure, thus: struct uart { unsigned baud : 3; unsigned parity : 2; unsigned unused : 2; unsigned interrupt_enable : 1; }; WebThis function illustrates many C program points: for loop not used for simple counting operation. x >>= 1 => x = x>> 1; for loop will repeatedly shift right x until x becomes 0. use expression evaluation of x & 01 to control if. x & 01 masks of 1st bit of x if this is 1 then count++ .
