Decode Status Register into Human-Readable Flags

Code

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

void decode_status(uint8_t status_reg) {
 const char *status_name[]{
    "Power On",
    "Error",
    "Tx Ready",
    "Rx Ready",
    "Overheat",
    "Undervoltage",
    "Timeout",
    "Reserved"};
    
 for(int i=0;i<8;i++){
    if(status_reg&(1<<i)){
        printf("%s\n",status_name[i]);
    }
 }
}
int main() {
    uint8_t reg;
    scanf("%hhu", &reg);
    decode_status(reg);
    // return 0;
}
