Figure 14. Internal Comparator Circuitry for Analog Test
The result of the analog comparison is strobed into D3 at the falling edge of an internal signal derived from
the input BLANK signal. In order to have stable inputs to the comparator, the DAC should be set to a constant
level between syncs. For normal operation, data flow check, and screen integrity test, D<7:4> must be set
to zero.
