Hi

I'm using STM32F103R4 and trying to read the IDR of portc but it only i get data for PC4 & PC5, so how i can figure it out

below my configuration
        GPIO_InitTypeDef  GPIO_InitStructure;
        RCC_APB2PeriphClockCmd(RCC_APB2Periph_GPIOC, ENABLE);
        GPIO_InitStructure.GPIO_Pin = GPIO_Pin_All;
        GPIO_InitStructure.GPIO_Mode = GPIO_Mode_IPD;
        GPIO_Init(GPIOC, &GPIO_InitStructure);


        while (1) {
            GPIOA-> ODR = GPIO_ReadInputData(GPIOC);
        }
