#167002 - Program in Assembler?? Responding to: ???'s previous message |
Alan:
Is your program in assembler language? If so then the 30H to 7FH are is not a hard and fast limit. You should be able to fully analyze the programs usage of register banks 1, 2 and 3, the boolean bit flags area, and the stack area size used. Based on that analysis you may find that more RAM of the 256 is available to you. Michael Karas |
