Decode Status Register into Human-Readable Flags

Code

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

void decode_status(uint8_t status_reg) {
        if(status_reg & (1 << 0)){
            printf("Power On\n");
        }
        if(status_reg & (1 << 1)){
            printf("Error\n");
        }
        if(status_reg & (1 << 2)){
            printf("Tx Ready\n");
        }
        if(status_reg & (1 << 3)){
            printf("Rx Ready\n");
        }
        if(status_reg & (1 << 4)){
            printf("Overheat\n");
        }
        if(status_reg & (1 << 5)){
            printf("Undervoltage\n");
        }
        if(status_reg & (1 << 6)){
            printf("Timeout\n");
        }
        if(status_reg & (1 << 7)){
            printf("Reserved\n");
        }
}

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