Note: 1. When serial data Spinv bit is set to low. (When the Spinv bit is set to high,
the polarities of the SPBLK and the SPSIG are inverted.)

OBP Detailed Timing Specifications
Figure 4 shows the OBP detailed timing specifications.
The OB period is from the fifth to the twelfth clock cycle after the OB pulse is input. The average of the black signal
level is taken for eight input cycles during the OB period and becomes the clamp level (DC standard).

OB pulse > 2 clock cycles This edge is used, when OBP pulse-width period is clamp-on.

(When the OBPinv is set to high, the polarity of the OBP is inverted.)
Note: 1. Shifts ±1 clock cycle depending on the OBP input timing.
