OSD FUNCTIONS
Table 11 outlines the OSD functions of the M37271MF-XXXSP.
The M37274MA-XXXSP incorporates an OSD circuit of 36 charac-
ters
12 lines. OSD is controlled by the OSD control register. There
are 3 display modes and they are selected by a block unit. The dis-
play modes are selected by block control register i (i = 1 to 12).
The features of each mode are described below.
