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

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