4.3. Display Memory
The TPU 3040 supports a variable number of display
memories, each 4 KByte large. One bank is used to
store the display information of the selected teletext
page. The bank location can be defined with the com-
mand DISPLAY_TTX_POINTER. Other banks can be
used to store any kind of display data in level 1 or level
2 format. Switching between these banks is fast and can
be programmed with the command DISPLAY_POINT-
ER. Bank switching allows generation of OSD menus
without affecting the teletext display.
