Hi:

Could you hlep provide the sn65dsi86 can support format as about:

SYNC_PULSE_VDO_MODE / SYNC_EVENT_VDO_MODE /BURST_VDO_MODE

after HSS and VSS signal, it need to swap to LP mode?

are these parameter about "HBP & HFP &HSA" a must by DSI86 ?

Hi,

The DSI86 supports both Sync_Pulse and Sync_Event mode. For the Sync Pulse type of timing event, the GPU will send VSYNC START (VSS), VSYNC END (VSE), HSYNC START (HSS), and HSYNC END (HSE) packets. For Sync Event type, the GPU will only send the sync start packets (VSS and HSS). For both types of timing events, the DSI86 will use the values programmed into its Video Registers to determine the sync end events (VSE and HSE).

Thanks

David

Hi David:

What about HFP and HBP during two mode? If GPU transfer HFP and HBP information in packet with Sync Event type, will DSI86 handle this information?

Hi,

Refer to Table 8-6

The DSI86 will recreate the HBP and HFP base on the value programmed into its video register.

Thanks

David
