Sorry, i dont get it.
If i have 32kB (7FFFh), then LJMP 8003h jumps to "out of space"?
Maybe i should change to address let's say jus after 4KB (0FFFh) - means 1003h,... (8xxx -> 1xxx)?

And what about start-up, if EA=0?

Lets say my program will start after vertor table(1033h).
should i write in the code, which will be put in XRAM the following?

ORG 0
LJMP MAIN_PROG

(vector table)
ORG 1003h ...
LJMP EX0isr
...

ORG 1033h
MAIN_PROG: ...
...


What about the ORG 0 used in BOOTSTRAP. Are'nt they overlaying?

I'm sorry again. It seems complicated to me.
Maybe there is something to read about it? I read everything i found about external memory.
