Start-up, Operation Modes, HW functions and Clock
The SCP1000 initialization sequence described in this section (and in Figure 2) is performed each
time the sensor is:
During the start-up the power supplies must stabilize in to specified range before configuration and
calibration data can be loaded from the non-volatile memory to volatile registers. The start-up
sequence is divided into 3 phases described below in Figure 2.
