Decode Status Register into Human-Readable Flags

Code

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

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

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