Use this page to select the level of startup code you want to produce, the memory model, and the appropriate floating point format support.
Note: This page is available only for S08/RS08 derivatives.
Note: The availability of the options appearing on the page, depends on the derivative or board selected.
The table below explains the options available on this page.
| Option | Description |
|---|---|
| Tiny | Assumes that data pointers have 8-bit addresses unless explicitly specified with the keyword __far. |
| Small | Use the Small memory model if both the code and the data fit into the 64-kilobyte address space. By default, all variables and functions are accessed with 16-bit addresses. The compiler supports banked functions or paged variables in this memory model, but all accesses must be explicitly handled. |
| Banked | Banked memory model uses banked function calls by default, but the default data access is still 16-bit. Because the overhead of the far function call is not very large, this memory model suits all applications with more than 64-kilobytes of code. Data paging can be used, however all far objects and pointers to them must be specially declared. |
| None | Select for the best code intensity. |
| Float is IEEE32, Double is IEEE32 optimized | All float and double variables are 32-bit IEEE32. Library is optimized, but loses some of the IEEE754 standard compliance. |
| Float is IEEE32, Double is IEEE64 optimized | All float variables are 32-bit/IEEE32 and Double variables are 64-bit/IEEE64. Library is optimized, but loses some of the IEEE754 standard compliance. |
| Minimal startup code | Produces the best code density. The startup code initializes the stack pointer and calls the main function. No initialization of global variables is done, giving you the best speed/code density and a fast startup time. The application code must address variable initialization. ANSI requires variable initialization and therefore this option is not ANSI compliant. |
| ANSI startup code | Initializes global variables/objects and calls the application main routine. |
