5.7.AUXILIARY FILES
A variety of startup files is provided with the Demo Kits. The function of these files is as follows:
1. STARTUP.A51:
This file provides memory and stack initialization. It is part of the Keil compiler package.
2. STARTUP_SECURE.A51:
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:
CLR 0xA8^7 ; Disable interrupts
MOV 0B2h,#40h ; Set security bit.
MOV 0E8h,#0FFh ; Refresh nonmaskable watchdog
3. 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.
5.8.INCLUDE/HEADER FILES
