It seems like it would have been worthwhile to have more configuration
bits. One to enable the new instructions, and two to enable the new
addressing mode, with selectable index size cutoff. Rather than using
0-5F for indexed, and 60-7F for access, they could have a few different
cutoffs. For instance, one program may make good use of more access ram,
but only have fairly small offsets from the stack mark, another be just
the opposite. Sort of like on the 6809 processor variables located within
15 bytes of the stack mark took one less instruction word than those =
located
at larger offsets. In that case if you knew what you were doing you =
defined
the most used local variables first so they had smaller offsets.
