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) {
   uint32_t mask = ((1U << 4) - 1);
   mask=mask << 8;    
   reg =reg& ~mask;                         
       reg |= ((baud & 0xF) << 8);           
     return reg;
}

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