Reset Sequence and Initialization

During the initial power-up state, an initialization time, tINIT_NS of 400 μs is the minimum requirement for the MIPI D-PHY receiver to function properly before an LP/HS data transfer (400 µs of initialization time is required when MIPI hard DPHY transmitter is used, you can adjust this timing depending on other transmitter's specifications). Another 100 μs of initial skew calibration time is needed after the INIT time expires. Typically, reset_pixel_n can be deasserted at any time after deassertion of other reset domains, but should be before the end of initialization and skew calibration. The output of valid pixel data can be decoded from the PPI interface after the initialization and skew calibration processes are completed. For any reset assertion event during user mode, you must follow the reinitialization sequence below for reset deassertion procedure.

The following figure describes the reset sequencing and initialization requirements.
