Decode Status Register into Human-Readable Flags

Code

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

 

void decode_status(uint8_t status_reg) {
    if (status_reg & 0x1) 
    {
        printf("Power On\n");
    }
    if (status_reg & 0x2) 
    {
        printf("Error\n");
    }
    if (status_reg & 0x4) 
    {
        printf("Tx Ready\n");
    }
    if (status_reg & 0x8) 
    {
        printf("Rx Ready\n");
    }
    if (status_reg & 0x10) 
    {
        printf("Overheat\n");
    }
    if (status_reg & 0x20) 
    {
        printf("Undervoltage\n");
    }
    if (status_reg & 0x40) 
    {
        printf("Timeout\n");
    }
    if (status_reg & 0x80)
    {
        printf("Reserved\n");
    }

}

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