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) {
    // Your code here
    uint32_t mask = (( 1 << 4)-1) << 8;
    reg = reg & ~mask;
    mask = 0; 
    mask = mask | baud ;
    mask = mask << 8;
   
    reg = reg | mask;

    
    return reg;
}

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