USER’S GUIDE

Chapter 6. USART Asynchronous Communications

6.1 INTRODUCTION

This chapter describes the USART Asynchronous Communications mode. USART

Asynchronous data and commands can be entered using a Basic Communications

window or by creating Script Commands.

It is assumed that the user is familiar with the USART Asynchronous protocol. For more

information see:

• USART, AUSART, or EUSART chapter of the PIC microcontroller data sheet of

interest

• A USART Asynchronous Communications tutorial is available on the Microchip

Technology web site. Click on the links: Support -> Getting Started -> PIC MCU

Tutorials -> USART - Using in Asynchronous Mode

• Several application notes are available on the Microchip Technology web site.
