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 < 9; 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);
