SN65DSI86: Suspend mode & PSR setting question

Bruce Lin_899

Part Number: SN65DSI86

Dear Expert

Just want to check if customer want to use suspend mode like 8.3.3.2, and had check the GPU and panel support this mode.

But they can not dynamic setting register in application. and Only can do register setting in initial condition through DSI.

So, i want to ask that does 0x5A bit 3 the VSTREAM_ENABLE.need to set to 1 manually after suspend mode every time?

Can DSI86 auto out off suspend mode without any register setting?

Thank you so much!

You need to set the PSR_EXIT_VIDEO bit . If the PSR_EXIT_VIDEO bit is set, then active video begins transmitting over the DisplayPort interface after the first vertical sync start (VSS) is detected on the DSI interface. If the PSR_EXIT_VIDEO bit is not set, software must enable the
VSTREAM_ENABLE bit. Then active video begins transmitting over the DisplayPort interface after the first vertical sync start.

Thanks
