VDD and VDDIO pins can be energized in any order. A power-on reset generator is built in which resets the logic
circuitry and the register values after the power-on sequence. The slope for ramp up time must be within the limits
given by t_- VDDramp and t_VDDIOramp. After powering up, the sensor settles in sleep mode (see also 3.3.9").
Holding any interface pin (SDI, SDO, SCK or CSB) at a logical high level when VDDIO is switched off can permanently
damage the device due caused by excessive current flow through the ESD protection diodes.
