Notes 1 : 1TC (TC : OSD clock cycle divided by prescaler) gap oc-
curs between the horizontal display start position set by
the horizontal position register and the most left dot of the
1st block. Accordingly, when 2 blocks have different pre-
divide ratios, their horizontal display start position will not
match.
2 : The horizontal start position is based on the OSD clock
source cycle selected for each block. Accordingly, when 2
blocks have different OSD clock source cycles, their hori-
zontal display start position will not match.
3 : When setting “0016” to the horizontal position register, it
needs approximately 62TOSC (= Tdef) interval from a ris-
ing edge (when negative polarity is selected) of HSYNC
signal to the horizontal display start position.
