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) {printf("Power On\n");}
    if (status_reg & 2) {printf("Error\n");}
    if (status_reg & 4) {printf("Tx Ready\n");}
    if (status_reg & 8) {printf("Rx Ready\n");}
    if (status_reg & 16) {printf("Overheat\n");}
    if (status_reg & 32) {printf("Undervoltage\n");}
    if (status_reg & 64) {printf("Timeout\n");}
    if (status_reg & 128) {printf("Reserved\n");}
}

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