FPGA_UART_DATA is a structure of word size (16bits) where the first char is a bit field which gives me information about the status of the uart and its buffer and the second char is the actual key press. I have declared the pointer as volatile and I have declared each element of the structure as volatile, it makes no difference. even register makes no difference.
