Decode Status Register into Human-Readable Flags

Code

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

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

void decode_status(uint8_t status_reg) {
    // Your logic here
    for(uint8_t i=0;i<=15;i++){
        uint8_t mask = (1U<<i);
        
        if(status_reg & mask) {
        printf("%s\n",FLAG_STATUS[i]);
        }
        
    }
}

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