Dear All, I am upgrading a piece of software, having an small interruppt routine triggered every 100us. I now have a problem with getting the CPU doing anything else... The system consists of a C167CR-LM running at 16 MHz with an external 8bit FLASH, non mux. I am considering moving the interrupt routine to internal RAM and execute it from there and thereby get a reduced execution time by a factor 2-3. I have been studying the application note 138, but finds it rather tricky, isn't there any easier way to do this? Is the code generated by the compiler relocatable or do I have to rewrite the routine in assembly code? Comments appriciated. /Rolf
Rolf, Mike did you solve this problem? I have the same one. I want to relocate function from ROM to XRAM using its pointer, but it don't want to start.
