38.1 Chip-specific UART information

38.1.1 UART2 Overview

This device contains a basic universal asynchronous receiver/transmitter (UART)
modules with DMA function support. Generally, these modules are used in RS-232,
RS-485, and other communications. This module supports LIN Slave operation.

38.2 Introduction

The UART allows asynchronous serial communication with peripheral devices and
CPUs.

38.2.1 Features

The UART includes the following features:
• Full-duplex operation
• Standard mark/space non-return-to-zero (NRZ) format
• 13-bit baud rate selection with /32 fractional divide, based on the module clock
frequency
• Programmable 8-bit or 9-bit data format
• Separately enabled transmitter and receiver
