As title.
I haven't been able to find that much info about it, but does the SROM feature provide any useful solutions?
See http://www.keil.com/support/docs/2374.htm
On the C166 the linker seems to create symbols that you can use in your source files using macros, the linker will fill in the addresses or sizes at link-time. See http://www.keil.com/support/man/docs/l166/l166_sections.htm but it contains a dead link to more SROM info at http://www.keil.com/support/man/docs/c166/c166_ap_srom.htm (already mailed the webmaster about this).
