Reset Sequence and Initialization

During the initial power-up state, an initialization time, tINIT_NS of 100 μs is the minimum requirement for the MIPI D-PHY receiver to function properly before an LP/HS data transfer (100 µs of initialization time is required when Efinix MIPI soft DPHY transmitter is used, you can adjust this timing depending on other transmitter's specifications). Typically, reset_pixel_n can be deasserted at any time after deassertion of other reset domains, but before the end of initialization process. The output of valid pixel data can be decoded from the PPI interface after the initialization process is completed. For any reset assertion event during user mode, you must follow the reinitialization sequence for reset deassertion procedure.

The following figure describes the reset sequencing and initialization requirements.
