43.5.4 Generic Long Packet Demux
The Generic Long Packet (GLP) contains three packet subclasses:
- NULL packet, data type set to 0x10
- Blanking data, data type set to 0x11
- Embedded 8-bit non-image data, data type set to 0x12
Null and blanking data packet content must be ignored by the application layer. Embedded 8-bit non-image data packets can be used to forward additional information from the camera to the host processor. These packets can be routed to the data pipe interface and read by the DMA interface or processor. The data payload must be a multiple of 8 bits.
| Packet | Data Type | Handler |
|---|---|---|
| Generic Long Packet (GLP) | Null | Null interrupt |
| Blanking data | Data pipe | |
| Embedded 8-bit non-image data | Data pipe | |
| Reserved | GLP Error interrupt reserved |
