Introduction
   The STR91xFA series of Flash MCUs is based on an ARM966E CPU core which executes code directly from its internal Flash memory at a rate of up to 96 MHz. To allow flexibility for a variety of applications and power management schemes, there are many configuration settings available to firmware during the initialization of the STR91xFA at start-up. This application note outlines the necessary steps to ensure the STR91xFA is configured for optimum performance for those applications which require the STR91xFA to operate at full speed and deliver the highest performance from the CPU core and highest bandwidth of data movement.
