Decode Status Register into Human-Readable Flags

Code

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

const char *status_names[8] = {
    "Power On",
    "Error",
    "Tx Ready",
    "Rx Ready",
    "Overheat",
    "Undervoltage",
    "Timeout",
    "Reserved"
};

void decode_status(uint8_t status_reg)
{
    for (int i = 0; i < 8; i++) {
        uint8_t bit = (status_reg >> i) & 1u;
        if (bit) {
            printf("%s\n", status_names[i]);
        }
    }
}

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