Pre-defined Symbols

Sets symbols using the SETA directive. The defined names are copied exactly as they are entered (case-sensitive). Each name may get optionally a value, for example: Check, NoExtRam, X1=1+5
Clears previous Define assignments that are entered in the options dialog of a higher Target or Group level.

Language / Code Generation

Enable Arm/Thumb Interworking
The code in the assembler source file allows calls between ARM and Thumb mode code.
Read-Only Position Independent
The code in the assembler source file is designed for position independent ROM constants.
Read-Write Position Independent
The code in the assembler source file is designed for position independent RAM variables.
Thumb Mode
Generate Thumb Code.
No Warnings
Disable warning messages.
Software Stack-Checking
The code in the assembler source file carries out software stack-limit checking.
Split Load and Store Multiple
An error message is generated when the instructions LDM/STM have more than 5 (more than 4 when the PC is changed) CPU registers.
