Decode Status Register into Human-Readable Flags

Code

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

void decode_status(uint8_t reg) 
{

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

for(int i=0; i<8; i++)
{
    if(reg & (1u << i))
    {
        printf("%s\n", flag[i]);
    }
}

}

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