Decode Status Register into Human-Readable Flags

Code

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

#define IS_BIT_SET(val, pos) (val & (1 << pos))

void decode_status(uint8_t status_reg) {
    // Your logic here
    if(IS_BIT_SET(status_reg, 0)) printf("Power On\n");
    if(IS_BIT_SET(status_reg, 1)) printf("Error\n");
    if(IS_BIT_SET(status_reg, 2)) printf("Tx Ready\n");
    if(IS_BIT_SET(status_reg, 3)) printf("Rx Ready\n");
    if(IS_BIT_SET(status_reg, 4)) printf("Overheat\n");
    if(IS_BIT_SET(status_reg, 5)) printf("Undervoltage\n");
    if(IS_BIT_SET(status_reg, 6)) printf("Timeout\n");
    if(IS_BIT_SET(status_reg, 7)) printf("Reserved\n");
}

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