Decode Status Register into Human-Readable Flags

Code

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

uint8_t is_bit_set(uint8_t reg, uint8_t pos)
{
    if(reg & (1 << pos))
    {
        return 1;
    }
    return 0;
}
const char* flag[] = 
{
    "Power On",
    "Error",
    "Tx Ready",
    "Rx Ready",
    "Overheat",
    "Undervoltage",
    "Timeout",
    "Reserved",
};

void decode_status(uint8_t status_reg) {
    int i = 0;
    while(status_reg > 0)
    {
        if(is_bit_set(status_reg, 0) == 1)
        {
            printf("%s\n", flag[i]);
        }
        status_reg >>= 1;
        i++;
    }
}

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