22.5. Test Pattern Generator II Control Registers
After reading the control data, the Test Pattern Generator II IP core generates a control packet that describes the following image data packet. When the output is interlaced, the control data is processed only before the first field of a frame, although a control packet is sent before each field.
Address | Register | Description |
---|---|---|
0 | Control | Bit 0 of this register is the Go bit.. Setting this bit to 0 causes the IP core to stop before control information is read. When you enable run-time control, the Go bit gets deasserted by default. If you do not enable run-time control, the Go is asserted by default. Bit 1 of this register enables or disables the black border in the bars test patterns. This bit gets deasserted (border disabled) at reset. All other bits are unused. |
1 | Status | Bit 0 of this register is the Status bit, all other bits are unused. The IP core sets this address to 0 between frames. The IP core sets this address to 1 while it is producing data and cannot be stopped. |
2 | Interrupt | Unused. |
3 | Reserved | Reserved. |
4 | Output Width | The width of the output frames or fields in pixels.
Note: Value from 32 up to the maximum specified in the parameter editor.
|
5 | Output Height | The progressive height of the output frames or fields in pixels.
Note: Value from 32 up to the maximum specified in the parameter editor.
|
6 | Output interlacing | The output interlacing standard. Set to 0 for progressive, 1 for interlacing with F0 first, and 2 for interlacing with f1 first. |
7 | Pattern select | The test pattern configuration to enable. Write 0 for configuration 0, 1 for configuration 1, and so on. |
8 | R/Y value | The value of the R (or Y) color sample when the test pattern is a uniform color background.
Note: Available only when the IP core is configured to produce a uniform color background and run-time control interface is enabled.
|
9 | G/Cb value | The value of the G (or Cb) color sample when the test pattern is a uniform color background.
Note: Available only when the IP core is configured to produce a uniform color background and run-time control interface is enabled.
|
10 | B/Cr value | The value of the B (or Cr) color sample when the test pattern is a uniform color background.
Note: Available only when the IP core is configured to produce a uniform color background and run-time control interface is enabled.
