Macro-Based Register Config Helper

Code

#include <stdio.h>
#include <stdint.h>

// Define macros here

uint16_t build_register(uint8_t enable, uint8_t mode, uint8_t speed) {
    
    uint8_t ans=0;
    ans |=(enable<<0);
    ans |=(mode<<1);
    ans |=(speed<<3);

    return ans;
}

int main() {
    uint8_t enable, mode, speed;
    scanf("%hhu %hhu %hhu", &enable, &mode, &speed);

    uint16_t reg = build_register(enable, mode, speed);
    printf("%u", reg);
    return 0;
}
