Rev. 1.0
The horizontal display start position is common to all blocks, and can
be set in 128 steps (where 1 step is 4TOSC, TOSC being the OSD
oscillation cycle) as values “0016” to “FF16” in bits 0 to 6 of the hori-
zontal position register (address 00D116). The horizontal position reg-
ister is shown in Figure 8.11.8.
Fig. 8.11.8 Horizontal Position Register
Notes 1 : 1TC (TC : OSD clock cycle divided in pre-divide circuit) gap occurs
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 dis-
play 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 horizontal display start position will
not match.
3 : When setting “0016” to the horizontal position register, it needs ap-
proximately 62TOSC (= Tdef) interval from a rising edge (when nega-
tive polarity is selected) of HSYNC signal to the horizontal display start
position.
