PRODUCTION DATA
RX port-specific register. The FPD-Link III Port Select register 0x4C configures which unique Rx port registers can be accessed by I2C read and write commands.
| BIT | FIELD | TYPE | DEFAULT | DESCRIPTION |
|---|---|---|---|---|
| 7:6 | RAW10_8BIT_CTL | R/W | 0x0 | Raw10 8-bit mode When Raw10 Mode is enabled for the port, the input data is processed as 8-bit data and packed accordingly for transmission over CSI. 00 : Normal Raw10 Mode 01 : Reserved 10 : 8-bit processing using upper 8 bits 11 : 8-bit processing using lower 8 bits |
| 5 | DISCARD_ON _PAR_ERR | R/W | 1 | Discard frames on Parity Error 0 : Forward packets with parity errors 1 : Truncate Frames if a parity error is detected |
| 4 | DISCARD_ON _LINE_SIZE | R/W | 0 | Discard frames on Line Size 0 : Allow changes in Line Size within packets 1 : Truncate Frames if a change in line size is detected |
| 3 | DISCARD_ON _FRAME_SIZE | R/W | 0 | Discard frames on change in Frame Size When enabled, a change in the number of lines in a frame will result in truncation of the packet. The device will resume forwarding video frames based on the PASS_THRESHOLD setting in the PORT_PASS_CTL register. 0 : Allow changes in Frame Size 1 : Truncate Frames if a change in frame size is detected |
| 2 | AUTO_POLARITY | R/W | 0 | Automatic Polarity Detection This register enables automatic polarity detection. When this bit is set, polarity of LineValid and FrameValid will be automatically detected from the incoming data. In this mode, at least one initial frame will be discarded to allow for proper detection of the incoming video. 1 : Automatically detect LV and FV polarity 0 : Use LV_POLARITY and FV_POLARITY register settings to determine polarity |
| 1 | LV_POLARITY | R/W | 0 | LineValid Polarity This register indicates the expected polarity for the LineValid indication received in Raw mode. 1 : LineValid is low for the duration of the video frame 0 : LineValid is high for the duration of the video frame |
| 0 | FV_POLARITY | R/W | 0 | FrameValid Polarity This register indicates the expected polarity for the FrameValid indication received in Raw mode. 1 : FrameValid is low for the duration of the video frame 0 : FrameValid is high for the duration of the video frame |
