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) {
    reg &= ~(0xFU << 8);          // Clear bits 8–11
    reg |= ((baud & 0xFU) << 8);  // Set new baud value
    return reg;
}

int main() {
    uint32_t reg;
    uint8_t baud;

    scanf("%u", &reg);
    scanf("%hhu", &baud);

    reg = set_baud_rate(reg, baud);

    printf("%u", reg);
    return 0;
}
