ISO examples
Note
In addition, the MVMode parameter in the DigitalConfig register allows giving more weight to low input
levels.
Note
MV Reception
To start a reception with majority voting function, assert CK high at the beginning of the response. Then
take data on every falling edge of DSYNC. Reception is stopped by asserting CK low on the last rising
edge of DSYNC. Data output are delayed by DecTimeRef (see next figure).
