Decode Status Register into Human-Readable Flags

Code

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

#define POWER_ON       (1U << 0)
#define ERROR          (1U << 1)
#define TX_READY       (1U << 2)
#define RX_READY       (1U << 3)
#define OVERHEAT       (1U << 4)
#define UNDERVOLTAGE   (1U << 5)
#define TIMEOUT        (1U << 6)
#define RESERVED       (1U << 7)

void decode_status(uint8_t status_reg) {
    // Your logic here
    if (status_reg & POWER_ON)       printf("Power On\n");
    if (status_reg & ERROR)          printf("Error\n");
    if (status_reg & TX_READY)       printf("Tx Ready\n");
    if (status_reg & RX_READY)       printf("Rx Ready\n");
    if (status_reg & OVERHEAT)       printf("Overheat\n");
    if (status_reg & UNDERVOLTAGE)   printf("Undervoltage\n");
    if (status_reg & TIMEOUT)        printf("Timeout\n");
    if (status_reg & RESERVED)       printf("Reserved\n");

}

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