Decode Status Register into Human-Readable Flags

Code

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

const char* names[8] {
    "Power On",
    "Error",
    "Tx Ready",
    "Rx Ready",
    "Overheat",
    "Undervoltage",
    "Timeout",
    "Reserved"
};

void decode_status(uint8_t status_reg) {
    for (int i=0; i<8; i++) {
        if ((status_reg >> i) & 1U) {
            printf(names[i]);
            printf("\n");
        }
    }
}

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