The main reason why "setb 0x94" has to be the first instruction is cause it selectes to execute code out of rom. Otherwise, it executes out of ram which does not have anycode in it. I have ensure that the initial state of p1.4 is high.

I understand Startup.a51 is called. However, I want to be able to change the location of of this start up code. I don't use any of the low interrupts vectors either.
