Each step is elaborated in the next sections as a small recipe or procedure to follow. Where

applicable, a reference to additional background information will be provided.

The configuration is split in a static and a dynamic part. The static part must be executed

once after every power-up or upon a static mode change. The dynamic part must be executed

at least once after every power-up and is grouped in a context to allow changing the operation

mode on the fly, as detailed in section 7.2.5. Subsequent steps cannot be skipped, e.g. GAIN

mode can be changed without changing IMG mode, but not the other way around.

Information

Useful are the optional paths to return to either the soft or hard reset state, which can be

taken to temporarily put the sensor in a lower consumption state without having to do a full

power cycle.

Attention

Not following these recommendations can lead to the sensor being in an unknown state with

unpredictable behavior.

Attention

A specific order and timing must be applied to the sensor supplies to guarantee a proper power-up

sequence and to avoid peak currents.

The overall power-up and reset release sequence is described in section 7.2.2. The sections

below describe in more detail the exact parts of that sequence.

Power-Up Sequence

Figure 65:

Power-Up Sequence

All external supplies start at 0 V and must ramp to their respective values as specified in

chapter 5 and section 7.2.1, respecting the order and the timing as shown in the Figure 65.

VDD12* must ramp-up first, let stead and finally ramp-up VDD33* and VDDPIX together, in
