OSD FUNCTIONS
Table 10 outlines the OSD functions of the M37271MF-XXXSP.
The M37271MF-XXXSP incorporates an OSD control circuit of 40
characters
16 lines. OSD is controlled by the OSD control regis-
ter. There are 3 display modes and they are selected by a block unit.
The display modes are selected by the block control register i (i = 1
to 6).
The features of each mode are described below.
