QUESTION

I've noticed that there are several startup files provided with the Keil tools. Which one should I use?

ANSWER

The startup requirements of most 8051 devices can be satisfied by the standard STARTUP.A51 startup code. There are, however, a number of devices with special options that must be configured at startup. Several new startup code files have been created to accommodate these devices.

If you fail to include startup code in your project, the linker uses the default startup code (STARTUP.A51) from the standard library.
