Decode Status Register into Human-Readable Flags

Code

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

void decode_status(uint8_t status_reg) 
{
    for(int i=0; i<8; i++)
    {
        uint8_t mask;
        mask = status_reg;
        mask &= (1<<i);
        if(mask == 1)
        printf("Power On\n");
        else if(mask == 2)
        printf("Error\n");
        else if(mask == 4)
        printf("Tx Ready\n");
        else if(mask == 8)
        printf("Rx Ready\n");
        else if(mask == 16)
        printf("Overheat\n");
        else if(mask == 32)
        printf("Undervoltage\n");
        else if(mask == 64)
        printf("Timeout\n");
        else if(mask == 128)
        printf("Reserved\n");
    }
    
}

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