Decode Status Register into Human-Readable Flags

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

#define check_bit(byte, n)  (byte & (1 << n))

void decode_status(uint8_t status_reg) {
    const char* status_flag [] = {
        "Power On",

        "Error",

        "Tx Ready",

        "Rx Ready",

        "Overheat",

        "Undervoltage",

        "Timeout",

        "Reserved"
    };
    for(int i = 0; i < 8; i++){
        if(check_bit(status_reg, i)){
            printf("%s\n", status_flag[i]);
        }
    }
}

int main() {
    uint8_t reg;
    scanf("%hhu", &reg);
    decode_status(reg);
    return 0;
}
