Commit | 31:0 | Write to any bits to trigger a commit of new motion adaptive deinterlacer settings. |
Name | Bits | Description |
Adjust Value | 15:0 | Applies the adjustment parameter multiplied by the calculated motion coefficient to either amplify or reduce the motion value. The adjustment parameter is represented by a 16-bit value. However, when the calculation completes, the resultant value shifts right by12 bits. To preserve the initially calculated motion coefficient unchanged, set the adjustment parameter to 0x1000. The default setting for this parameter is 0x2000. To achieve optimal performance, tune this parameter according to the specific requirements of your application. Begin with an initial value of 0x6000. |
Unused | 31:16 | Unused. |
Name | Bits | Description |
Control Value | 1:0 | The control register has two bits to configure the operational mode of the motion adaptive deinterlacer. Setting bit 0 to 1 activates the deinterlacer to perform either bob or weave calculations. Within this context, if bit 0 is set to 1, the state of bit 1 determines the specific operation. A value of 0 for bit 1 initiates a weave operation. A value of 1 for bit 1 triggers a bob operation. If bit 0 is not set to 1, the value of bit 1 is disregarded. |
Unused | 31:2 | Unused. |
When you turn on lite mode, registers are RW only if you turn on Debug features, otherwise they are WO. For full, turn off lite mode.
