TEST (Test mode)
Switches DAC1, 2, and 3 outputs. Also used to test IC for shipping.
Switches horizontal frequency.
Switches output from pin 16/28. When set to 00, 01, or 10, outputs HD/VD without synchronization.
When set to 11, outputs HD/VD from the sync circuit. (Note) Synchronized VD width will change, when
HD PHASE will be changed.
Switches output from pin 19/29. When set to 00, 01, or 10, outputs HD/VD without synchronization.
When set to 11, outputs HD/VD from the sync circuit.
Switches sync separation level of pin 24/26. Set values are the levels from sync tip. Sync separation level
is changed according to the ratio of H-SYNC width during 1H period.
Controls 2-bit DAC (pin 12).
Controls 2-bit DAC (pin 25).
Controls open collector 1-bit DAC (pin 30).
*(0): DAC outputs are used as DAC.
