IF_MD 1:0 w Interface Mode on IFA,IFB,IFC
Any derivate can be configurated to operate in any of the
four following protocols on the IFA, IFB and IFC outputs.
Reconfiguration is required at every start-up, else the
default protocol of the derivate will be used.
SSC interface is always active in parallel on pins SCK,
CSQ and DATA.

1) In SPC interface configuration, the sensor’s digital signal processing unit (DSPU) runs only when receiving a SPC trigger
pulse on the IFA pin (see Figure 6-12). This means that changes to register settings are applied and also the angle (AVAL)
register is updated only after a trigger pulse.
