2.16 OSD Functions
Table 2.16.1 outlines the OSD functions of this microcomputer. This OSD function can display the follow-
ing: the block display (32 characters ! 16 lines or 42 characters ! 16 lines) and the SPRITE display, and
can display the both display at the same time. There are 3 display 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 display are
described below.
Note: When using OSD function, select “No-division mode” as BCLK operating mode and set the main
clock frequency to f(XIN) = 10 MHz.

Notes 1: The character size is specified with dot size and pre-divide ratio (refer to “2.16.3 Dot Size”).
2: As for SPRITE display, OUT2 is not output.
3: As for SPRITE display, the window function does not operate.
4: The divide ratio of the frequency divider (the pre-divide circuit) is referred as “pre-divide ratio” hereafter.
