Decode Status Register into Human-Readable Flags

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

void decode_status(uint8_t reg) {
   const char *labels[] = {
   "Power On",      // Bit 0
        "Error",         // Bit 1
        "Tx Ready",      // Bit 2
        "Rx Ready",      // Bit 3
        "Overheat",      // Bit 4
        "Undervoltage",  // Bit 5
        "Timeout",       // Bit 6
        "Reserved"   
   };
   //printf("Status Register (0x%02X) Flags:\n", reg);
   // int active_flags = 0;
    for(int i = 0; i < 8; i++){
        if(reg & (1 << i)){
            printf("%s\n", labels[i]);
           // active_flags++;
        }
    }
    
   // if (active_flags == 0){
       
    //    printf("- No flags active\n"); 
   // }

}

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