Decode Status Register into Human-Readable Flags

Code

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

void decode_status(uint8_t reg) {
    // Your logic here
    if((reg >> 0) & 1U) printf("Power On\n");
    if((reg >> 1) & 1U) printf("Error\n");
    if((reg >> 2) & 1U) printf("Tx Ready\n");
    if((reg >> 3) & 1U) printf("Rx Ready\n");
    if((reg >> 4) & 1U) printf("Overheat\n");
    if((reg >> 5) & 1U) printf("Undervoltage\n");
    if((reg >> 6) & 1U) printf("Timeout\n");
    if((reg >> 7) & 1U) printf("Reserved\n");
    return;
}

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