Decode Status Register into Human-Readable Flags

Code

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

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

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