and ON-SCREEN DISPLAY CONTROLLER
12.11 OSD FUNCTIONS
Table 12.11.1 outlines the OSD functions.
This OSD function can display the following: the block display (32
characters ! 16 lines), the SPRITE display. And besides, the func-
tion can display the both display at the same time. There are 3 dis-
play modes and they are selected by a block unit. The display modes
are selected by block control register i (i = 1 to 16).
The features of each mode are described below.
