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
    // 1. Clear
    uint32_t mask = (0xf << 8);
    reg &= ~mask;

    // 2. Set
    reg |= ((baud & 0xf) << 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;
}

Solving Approach

Step1. clear

Step2. set

clear -> set is a format for setting a field
