DATASHEET
To leave Doze mode and enter Active mode this can be done by a simple touch on any button.
For some applications a single button touch might cause undesired wakening up and Active mode would be
entered too often.
The SX8635 offers therefore a smart wake-up sequence feature in which the user needs to touch and release a
correct sequence of buttons before Active mode will be entered. This is explained in more detail in the Wake-Up
Sequence section.
The host can decide to force the operating mode by issuing commands over the I2C (using register
CompOpMode) and take fully control of the SX8635.
The diagram in Figure 8 shows the available operation modes and the possible transitions.
