(15) On-chip Color Bar
The AK8817 can output Color Bar signal.
Color Bar signal to be generated has 100 % amplitude and 75 % Saturation levels.
Color Bar signal is output by setting register.
When to output Color Bar signal, there are 2 modes of operation – one is external Sync timing mode for normal
operation, and the other is internal self-operation mode.
In internal self-operating mode, required timing is internally generated automatically. Namely, it is no need to input
synchronization timing from outside of the chip.
Operation mode setting is done by Control 1 Register .
When BBG-bit is set, BBG-bit is prioritized ( Black Burst is output ).

(16) Black Burst Signal generation function
The AK8817 can output Black Burst signal ( Black level output ).
When to output Black Burst signal, there are 2 modes of operation – one is external Sync timing mode for normal
operation , and the other is internal self-operation mode.
In internal self-operation mode, required timing is internally generated automatically. Namely, it is no need to input
synchronization timing from outside of the chip.
When BBG-bit of [ Control 1 Register ] is set to “1”, same operation is processed as in the case where fixed-16 Y signal
and
fixed-128 Cb / Cr signal outputs are input.
Operation mode setting is done by Control 1 Register setting.
