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 use this
driver.
Section 10 of this application note describes an OS independent hardware abstraction layer
(HAL) for the SPEAr UART which you can use as a starting point for developing your own
HAL code.
