Answer 1

we all work on art in diifrent types 

Answer 2

The Universal Asynchronous Receiver Transmitter (UART) is a popular and widely-used device for data communication in the field of telecommunication. There are different versions of UARTs in the industry. Some of them contain FIFOs for the receiver/transmitter data buffering and some of them have the 9 data bits mode (start bit + 9 data
bits + parity + stop bits). This reference design describes a fully configurable UART optimized for and implemented
in a variety of Lattice devices, which offer superior performance and architecture compared to existing semiconductor ASSPs (application-specific standard products).
