The information contained in this message is confidential and is intended for
ed to be flagged as requiring
synchronisation with a tearing effect control signal - either the inband
method or a dedicated line. I suspect many hardware implementations will have
a specific method for transferring pixel data in a DSI command mode transfer.
The command sending period during video mode should probably be configurable
on a per-transfer basis. Some commands have to be synchronised with vertical
blanking, others do not. This could perhaps be combined with a wider
configuration option for a given panel or interface. Similarly, selection of
low power (LP) and high speed (HS) mode on a per-transfer basis can be needed
for some panels.
Is there a mechanism for controlling ultra-low power state (ULPS) entry? Also,
is there a method for sending arbitrary trigger messages (eg the reset
trigger)?
Thanks,
Bert.
