23. Set Baud Rate Field in Control Register

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


#define BAUD_UPDATE(reg,baud) reg = (reg & ~0xF00) | (baud << 8)

uint32_t set_baud_rate(uint32_t reg, uint8_t baud) {
    // Your code here
    BAUD_UPDATE(reg,baud);
    return reg;
}

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