Bit Operations using Macros

Code

#include <stdio.h>
#include <stdint.h>

// Bit manipulation macros
#define SET_BIT(REG, BIT)     ((REG) |=  (1U << (BIT)))
#define CLEAR_BIT(REG, BIT)   ((REG) &= ~(1U << (BIT)))
#define TOGGLE_BIT(REG, BIT)  ((REG) ^=  (1U << (BIT)))

uint8_t modify_register(uint8_t reg) {
    
    SET_BIT(reg, 2);
    SET_BIT(reg, 7);


    CLEAR_BIT(reg, 3);

   
    TOGGLE_BIT(reg, 5);

    return reg;
}

int main() {
    uint8_t reg;
    scanf("%hhu", &reg); 

    uint8_t result = modify_register(reg);
    printf("%u", result); 

    return 0;
}
