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 = ~(0xF << 8); // mask with 0's on update bit positions
    reg &= mask;
    // print_binary(reg);    
    reg |= (baud)<<8;
    // print_binary(reg);
    return reg ;
}

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