Set Baud Rate Field in Control Register

Code

#include <stdio.h>
#include <stdint.h>
#define CLEAR_REG_BAUDRATE(reg) (reg &= ~(15U << 11))
uint32_t set_baud_rate(uint32_t reg, uint8_t baud) {
    reg &= ~((uint32_t)15U << 8);
    reg |= (uint32_t)baud << 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;
}
