is not good enough.
Just because an application has only one interrupt source, that doesn't
necessarily make it trivial.
(And the Pic18 range has prioritised interrupts so you can do a jitter-free
timer interrupt while
other interrupts are happenning)

You've snipped the next bit of my paragraph - "The difference between
upper and lower registers is very annoying, but hardly difficult to
remember - only upper registers can use immediate addressing modes." I
was not referring to the immediate opcode issue here, nor the limited
pointer modes (which I think is a far bigger problem than the immediate
addressing modes, and which should have been a priority when the cpu was
Actually, now that I look at the datasheets again instead of relying on
memory, I see that about the only one that was fixed was (E)LPM, which
used to rely on a particular register R0. I had thought that the
multiply instructions (which use specific registers R0:R1) was also made
more general, but I was wrong there.
