- * The STARTUP.S code is executed after CPU Reset. This file may be
- * translated with the following SET symbols. In uVision these SET
- * symbols are entered under Options - ASM - Set.
- *
- * REMAP: when set the startup code initializes the register MEMMAP
- * which overwrites the settings of the CPU configuration pins. The
- * startup and interrupt vectors are remapped from:
- * 0x00000000 default setting (not remapped)
- * 0x80000000 when EXTMEM_MODE is used
- * 0x40000000 when RAM_MODE is used
- *
- * EXTMEM_MODE: when set the device is configured for code execution
- * from external memory starting at address 0x80000000. The startup
- * vectors are located to 0x80000000.
- *
- * RAM_MODE: when set the device is configured for code execution
- * from on-chip RAM starting at address 0x40000000. The startup
- * vectors are located to 0x40000000.
