The Z90255 takes full advantage of ZilogÕs Z8 expanded register file space to
offer greater flexibility in creating a user-friendly On-Screen Display (OSD).
Three basic addressing spaces are available: Program memory, Video RAM
(VRAM) and the Register file. The register file is composed of 300 bytes of
general-purpose registers, 16 control and status registers, one I/O port register
and three reserved registers.
