Decode Status Register into Human-Readable Flags

Code

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

#define IS_BIT_SET(reg, b) ((*reg & (1 << (b))) ? 1 : 0)

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;
}
