SECTION statement and the CHIP/FAST attribute

Apollo · 14 June 2013, 18:09

Is it true that there is no kind of a 'fallback' declaring a section to be located in fast mem, e.g.

Code:

section myCode,code,fast

So, it won't be automatically located into chip mem? So, is there an order declaring it only as

Code:

section myCode,Code

Takes fastmem precedence over chipmem regarding the latter section statement? Sorry for asking this, but I didn't found precise information.

if you declare _F or fast (depending on the used assembler), the section in question will be loaded to fast memory, if no fast mem is available, an out of memory error will occur. If you omit the _F/fast specifier, the section will be loaded to fast mem if available, otherwise chip mem will be used.

Thank you. Question is answered.

For completeness:

_P (or omitted): fastmem if available, else chipmem
_F: fastmem, forced
_C: chipmem, forced (for data accessed by custom chips, such as graphics, samples, copper lists).
