SINGLE-CHIP 8-BIT CMOS MICROCOMPUTER with CLOSED CAPTION DECODER
and ON-SCREEN DISPLAY CONTROLLER
M37274MA-XXXSP
PRELIMINARY

Notes 1 :
1T
C
(T
C
: 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.
Ordinaly, this gap is 1T
C
regardless of character sizes,
however, the gap is 1.5T
C
only when the character size is
1.5T
C
.
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.
