STK6005
rotational OSD is defined, the bit map of fonts should rotate by 90 degrees and be programmed for each
font of 36 bytes by 18 dots (3 bytes) * 12 lines. The char. and attribute contents of the OSD window
should also be programmed from bottom at a corner to the left first. (from bottom to top and then from left
to right) It should be noted that the registers for defining the OSD window are swapped between the
horizontal and vertical.
5.14 Auto-Adjustment
To set a Color Threshold
Set the threshold of input signals before using the auto-detecting function to avoid the noise of input signals
affecting the measurement results. Registers GateR, GateG, and GateB mean the threshold values for red,
green, and blue of input signals. The auto-detecting circuit will allow the input signals with all colors
levels higher than their thresholds level, or otherwise the input signals will not be included in the
measurement.
To
set a Measurement Window
Set the measurement window before using the auto-detecting function to avoid the noise of input signals among
some certain positions or to measure the region of interests. Set register SelWDE to switch the active region
defined by AWinH/V registers or internal DE.
To select an Input Source
Set a register SelHV to select H-Sync and V-Sync input sources for timing measurement. Set registers
SelVCnt and SelHCnt to select horizontal and vertical clocks for timing measurement.
Source Timing Measurement
STK6005 provides the following source timing data for auto-adjustment
1. HCT: A 16-bit value indicates the 16-cycle period of selected input H-Sync signal.
The selected input clock RefCLK or VCLK is used to measure the period.
This value will be updated in each frame.
2. VCT: A 12-bit value indicates the period of selected input V-Sync signal.
The period can be measured by the input horizontal line or by 144 * RefCLKs.
This value will be updated in each frame.
