Table 4: Pages Stored in Memory in the Four Different Modes of Operation

with Sub-Page Mode Selected and Menu Page Mode not Selected
2.6 Menu Page Mode
When the decoder is set to menu mode, it reserves two pages of memory for uses other than receiving
teletext. The memory can be used for:
Menu pages for on-screen displays
Packet 8/30 format 2 data storage for PDC applications
Packet 26 storage for PDC applications
General purpose storage.
When the menu page is set, menus and on-screen displays can be made in either menu page 0 (store
6) or menu page 1 (store 7) by writing the appropriate characters into the teletext memory. When
packet 8/30 format 2 storage is selected, each of the four possible interleaves are stored separately in
menu page 1.
The controlling microprocessor can read and write bytes to the menu page and can therefore use them
for general purpose storage if required.
