Decode Status Register into Human-Readable Flags

Code

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

void decode_status(uint8_t status_reg) {
    for(int i=0; i<8; i++){
        if(status_reg  & (1<<i))
        {
            switch(i) {
                case 0:printf("Power On\n");
                break;
                case 1: printf("Error\n");
                break;
                case 2: printf("Tx Ready\n");
                break;
                case 3:printf("Rx Ready\n");
                break;
                case 4:printf("Overheat\n");
                break;
                case 5:printf("Undervoltage\n");
                break;
                case 6:printf("Timeout\n");
                break;
                case 7:printf("Reserved\n");
                break;
            }
        }
    }
}

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