Decode Status Register into Human-Readable Flags

Code

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

void decode_status(uint8_t status_reg) 
{
    // Your logic here
    static uint8_t index = 0;
    while(index <= 8)
    {
        if(status_reg & (1<<index))
        {
            switch(index)
            {
                case 0:
                    printf("Power On\n");
                    break;
                
                case 1:
                   printf("Error\n");
                   break; 
                
                case 2:
                   printf("Tx Ready\n");
                   break; 

                case 3:
                   printf("Rx Ready\n");
                   break; 

                case 4:
                   printf("Overheat\n");
                   break; 

                case 5:
                   printf("Undervoltage\n");
                   break; 

                case 6:
                   printf("Timeout\n");
                   break; 

                case 7:
