Application note
Using the UART interfaces in the SPEAr embedded MPU family


Introduction
The SPEAr embedded MPU family is a family of configurable MPUs, based on the ARM926
CPU core. Each member of the SPEAr MPU family has one or more embedded ARM PL011
UARTs for asynchronous communications. This application note describes how to configure
the UART and transmit and receive data.
A Linux driver is available in the SPEAr Linux support package (LSP), refer to the SPEAR
Linux support package (LSP) user manual (UM0851) for a description of how to
