## Overview

This is a small Verilog UART design: a transmitter and receiver implement the documented asynchronous frame, with loopback connecting TX output to RX input for end-to-end transfer. The README documents these interfaces and test scenarios; no RTL excerpts were available to confirm finer-grained behavior. Testbenches and simulation artifacts are excluded from this runtime architecture.

Main entry points: [`rtl/uart_tx.v`](https://github.com/vidhyamadhavivemuri-spec/uart-communication-protocol-verilog/blob/main/rtl/uart_tx.v) (UART transmitter), [`rtl/uart_rx.v`](https://github.com/vidhyamadhavivemuri-spec/uart-communication-protocol-verilog/blob/main/rtl/uart_rx.v) (UART receiver)

## Components

### UART RTL

- [UART transmitter](https://github.com/vidhyamadhavivemuri-spec/uart-communication-protocol-verilog/blob/main/rtl/uart_tx.v): `rtl/uart_tx.v`
- [UART receiver](https://github.com/vidhyamadhavivemuri-spec/uart-communication-protocol-verilog/blob/main/rtl/uart_rx.v): `rtl/uart_rx.v`

### Other components

- **Data source**
- **Received data**

## Connections

- Data source → UART transmitter: provides data
- UART transmitter → UART receiver: serial data
- UART receiver → Received data: delivers data
