Enhanced TV microcontrollers with
On-Screen Display (OSD)
SAA567x; SAA569x

MOVX memory
The normal 80C51 external memory area has been
mapped internally to the device (see Fig.8). This means
that the MOVX instruction accesses memory internal to
the device.

MOVX
SPACE PAGE SELECTION
The MOVX RAM page pointer is used to select one of the
256 pages within the MOVX address space, not all pages
are allocated, refer to Fig.9 for further detail. A page
consists of 256 consecutive bytes. XRAMP only works
with internal MOVX memory.

(1) Both SAA567x; SAA569x 128 and 192 kbytes have 12 kbytes of Display memory.
(2) 0800H to 1FFFH are mapped into 6 kbytes of Bank 0 of external RAM. An external RAM is required to be able to address
this memory space (refer to Section 20 and Section 30.1).
(3) Both SAA567x; SAA569x 128 and 192 kbytes have 2 kbytes of Data RAM.
(4) Display RAM for Closed Caption and Text is shared.
