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 = ((1U << 4) - 1) << 8;//4 because baud val is 4 bits and 8 because it is given in question that its the position
    reg &= ~(mask);

    reg |= 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;
}
