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 64:

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. Supplies that are shown to

be ramping at the same time may also be ramped up one by one.
