Set Baud Rate Field in Control Register

Code

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

uint32_t set_baud_rate(uint32_t reg, uint8_t baud) {
    for(int i = 0; i < 4; i++){
        uint8_t bit = (baud >> i) & 1;
        reg &= ~(1 << (8 + i));
        reg |= (bit << (8 + i));
    }
    return reg;
}

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