STARTUP.A51:
This file provides memory and stack initialization. It is part of the Keil compiler package.
This file is almost identical to STARTUP.A51. The only difference is that this variation sets the SECURE bit.
This bit enables security provisions that prevent external reading of flash memory and CE program memory.
The code segment below sets the security bit located at SFR register address 0xB2:
STARTUP1:
INIT.A51:
A secondary startup file. It is part of the Keil compiler package. This code is executed, if the application
program contains initialized variables at file level.
STARTUP_BOOT.A51:
This startup file is to be used when the code is to be compiled as a bootloader.
