#101653 - maybe like this
Responding to: ???'s previous message
hi,

wiki glossary said:

XDATA
Indirectly-accessible memory with MOVX (usually external
RAM or ROM). If such is available, it refers also to a RAM
(in excess of IRAM) integrated on chip, again accessed by MOVX.


while I quite agree I would say somehow different:
XDATA
In program model: Type of data space located
in expanded indirectly-accessible memory
(see XRAM) accessed with MOVX.

XRAM
Physical term: Expanded indirectly-accessible memory.
This type of memory is accessed via MOVX instructions.
It may be realized as external RAM/ROM as well integrated on chip.
..or something like it.

Regards,
Oleg
