All synchronous display controls are generated on base of an internal generated “local start point”. The
synchronous display controls can be placed on time axis with DI’s offset, up and down parameters. The
display access can be whole number of DI clock (Tdiclk) only. The IPP_DATA can not be moved relative
to the local start point.

VSYNC—Vertical synchronization
DRDY—Active data
DI_CLK internal DI clock, used for calculation of other controls.
IPP_DISP_CLK latches data into the panel on its negative edge (when positive polarity is
selected). In active mode, IPP_DISP_CLK runs continuously.
HSYNC causes the panel to start a new line. (Usually IPP_PIN_2 is used as HSYNC)
VSYNC causes the panel to start a new frame. It always encompasses at least one HSYNC pulse.
(Usually IPP_PIN_3 is used as VSYNC)
DRDY acts like an output enable signal to the CRT display. This output enables the data to be
shifted onto the display. When disabled, the data is invalid and the trace is off.
(For DRDY can be used either synchronous or asynchronous generic purpose pin as well.)
