Decode Status Register into Human-Readable Flags

Code

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

void decode_status(uint8_t status_reg)
{
   uint8_t pos = 0;
   while(pos<=7)
   {
    if(status_reg & (1<<pos))
    {
      if(pos == 7)
         printf("Reserved\n");
      if(pos == 6)
         printf("Timeout\n");
       if(pos == 5)
         printf("Undervoltage\n");
       if(pos == 4)
         printf("Overheat\n");
       if(pos == 3)
         printf("Rx Ready\n");
        if(pos == 2)
         printf("Tx Ready\n");
        if(pos == 1)
         printf("Error\n");
        if(pos == 0)
         printf("Power On\n");
    }
    
    pos = pos + 1;
   }
}

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