Decode Status Register into Human-Readable Flags

Code

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

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

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