8.4.8 CSI-2 Data Identifier
The DS90UH940-Q1 MIPI CSI-2 protocol interface transmits the data identifier byte containing the values for the
virtual channel ID (VC) and data type (DT) for the application specific payload data, as shown in Figure 31. The
virtual channel ID is contained in the 2 MSBs of the data identifier byte and identify the data as directed to one of
four virtual channels. The value of the data type is contained in the 6 LSBs of the data identifier byte.
• CSIIA_{0x6C}_0x2E[7:6] CSI_VC_ID: Configures the virtual ID linked to the current context.
• CSICFG1_0x6B[7:4] OFMT: Configures the data format linked to the current context.
