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) {
    uint16_t val=0;
    val=val|enable;
    uint8_t bit=mode;
    bit=bit<<1;
    val|=bit;
    bit=speed;
    bit=bit<<3;
    val|=bit;

    return val;
}

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;
}
