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);        // baud field = 8 bits at position 8
    reg = reg & mask;                     // clear old baud bits
    reg =  reg| (baud << 8);     // insert new baud value
    return reg;
}

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