Startup Code

Startup Code is the program code that executes immediately after reset. The startup code includes:

• The Reset Vector.
• Interrupt and Fast Interrupt Vectors.
• Code to Clear Memory.
• Code to Initialize Global Variables.

There are several different folders available (in \KEIL\ARM\STARTUP\) that include the startup code (STARTUP.S) for various ARM device variants. You should include a copy of the appropriate startup file in your project.

• \KEIL\ARM\STARTUP\ADI\STARTUP.S contains the startup code for Analog Devices ADuC702x chips.
• \KEIL\ARM\STARTUP\ATMEL\STARTUP.S contains the startup code for Atmel AT91 devices.
• \KEIL\ARM\STARTUP\PHILIPS\STARTUP.S contains the startup code for the Philips LPC2000 devices.
• \KEIL\ARM\STARTUP\SHARP\STARTUP.S contains the startup code for the Sharp LH754xx devices.
