Set Baud Rate Field in Control Register

Code

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

#define set_bit(reg, index)   ((reg) | (1 << (index)))
#define clear_bit(reg, index) ((reg) & ~(1 << (index)))

uint32_t set_baud_rate(uint32_t reg, uint8_t baud) {
    // Your code here
    for (int i = 8; i < 12; ++i) {
        reg = (baud&1) ? set_bit(reg, i) : clear_bit(reg, i);
        baud >>= 1;
    }
    return reg;
}

int main() {
    uint32_t reg;
    uint8_t baud;
    scanf("%u %hhu", &reg, &baud);
    printf("%u", set_baud_rate(reg, baud));
    return 0;
}
