On-Screen DisplayStandard and Extended Display ModesMN102H75K/F75K/85K/F85K LSI User Manual Panasonic Semiconductor Development Company159Panasonic7.6 Standard and Extended Display ModesTwo modes are available for the graphics and cursor layers, standard andextended. In extended mode, the cursor layer can display four grouped graphictiles rather than one. The graphics layer can display tiles that are two pixels tallerthan those used in standard mode, giving the graphic tiles the same dimensions asthe characters in the text layer.7.6.1 Cursor Layer Display ModesThe size of the cursor in the cursor layer is programmable to 16W x 16H pixels instandard mode and 32W x 32H pixels in extended mode. Select the mode for thislayer in the SPEXT bit of the OSD2 register (x’007F08’).To create a graphic for the cursor layer in extended mode, combine four 16 x 16tiles. They are ordered as follows: (1) upper left, (2) upper right, (3) lower left,and (4) lower right. Set the pointers to these tiles in cursor tile code registers 0 to3 (STC0–3), where STC0 corresponds to tile (1). Table 7-4 shows the associatedtiles and registers.A. Standard Mode (16W x 16H) B.
