3.1.5.1 Write Parameters

Table 3-6 describes the write parameters.

Table 3-6 Write Parameters
MSB Byte 1 LSB
b7 b6 b5 b4 b3 b2 b1 b0
Byte 1 Operating Mode
00h External Video Mode
01h Test Pattern Generator Mode
02h Splash Screen Mode
03h - FFh Reserved

The other operating modes have associated commands which are only applicable to that mode and must be run to properly configure the selected mode. The associated commands are listed below:

Note: Only RGB (and not YCbCr) format is supported in splash pattern mode.

The table below show the source specific associated commands, where ‘Y’ represents a valid source selection and ‘N’ implies that the command is not supported by the selected source.

Table 3-7 Source Specific Associated Commands
Source Specific Associated Commands Display Modes
External Video Port Test Pattern Generator Splash Screen
Write External Video Source Format Select Y N N
Write External Input Image Size Y N N
Write Test Pattern Select N Y N
Write Splash Screen Select N N Y
Write Splash Screen Execute N N Y(1)
(1) The Write Splash Screen Execute command is special in that there is no maintained state or history. Thus, this command has no “settings” to be stored and reused by the system.

It is recommended that the source associated commands be sent prior to sending the Write Operating Mode Select command. These commands (except for Write Splash Screen Execute) describe the unique characteristics of their associated source, and once these settings have been defined, they are stored in a volatile manner. When source associated commands are sent when that source is not active, the controller software saves the new settings, but does not execute these commands. When that source becomes active (via the Write Operating Mode Select command), the controller applies these settings. Each time an operating mode selection is made , the system retrieves the settings defined previously and automatically applies them. As such, the user only needs to send these associated commands when the source first needs to be defined, or when the source characteristics for that port need to be changed. It is important to note that the appropriate associated commands must be updated when source characteristics change. See below for examples to configure different operating modes.

The rest of the commands that apply to image setup are those commands whose settings are applicable across all source selections, and indeed, these command settings would typically remain the same across the different Operating Mode selections. Sometimes the values for these commands are the same across the different input source types, but this does not indicate that hardware settings have not changed. For example, if the display image size is set to 720p and the external port input source size is set to VGA, the input scales up to the display size of 720p. When splash screen is selected, the controller modifies the settings specified by Write Image Crop (10h) . The controller displays these settings at the resolution specified by Write Display Size (12h). Therefore, the scale settings must be changed. The controller software manages the underlying hardware settings. An example is shown below:

  1. User sends the following commands (active Input Source = Test Pattern Generator)
    1. Write Image Freeze = Freeze
    2. Write External Video Source Format Select (settings stored, command not executed)
    3. Write External Video Chroma Processing Select (settings stored, command not executed)
    4. Write External Input Image Size (settings stored, command not executed)
    5. Write Operating Mode Select = External Port (see the next step)
    6. Write Image Freeze = Unfreeze
  2. When the Write Operating Mode Select command is received, software applies the settings from these External Video Port associated commands.
    1. External Video Source Format Select
    2. External Video Chroma Processing Select
    3. External Input Image Size
    4. External Parallel Manual Image Framing (as appropriate – that is, if parallel port selected)
    5. External CPU Video Sync Mode (as appropriate – that is, if CPU port selected)

If source associated commands are sent for a source that is already active, the controller software will execute these commands when received. An example is shown below:

  1. User sends the following commands (active Input Source = External Video Port)
    1. Write Image Freeze = Freeze
    2. Write External Video Source Format Select (command executed)
    3. Write External Video Chroma Processing Select (command executed)
    4. Write Image Freeze = Unfreeze

Refer to Write Image Freeze (1Ah) for information on hiding on-screen artifacts when selecting an input source.
