Set Baud Rate Field in Control Register

Code

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

constexpr uint32_t baud_mask_pos =  8;
constexpr uint32_t baud_mask = (0x0F << baud_mask_pos);

uint32_t set_baud_rate(uint32_t reg, uint8_t baud) {
    // Your code here
    reg &= ~(baud_mask);
    return reg |= (baud << baud_mask_pos);
}

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