5.4.1.5.9.9 MinFrequencyRaw
Name:
MinFrequencyRaw01
This register is used to configure the lowest frequency of the raw signal to be evaluated for the individual channels.
This configuration only needs to be set for channels whose EnableVelocityCalculation bit has been set (configured
in the
"SensorConfig" on page 158
register).
Bit EnableVelocityCalculation = 0
The following minimum values based on the maximum frequency (
see "MaxFrequencyRaw" on page 186
) are
used: This table shows the minimum MinFrequencyRaw based on MaxFrequencyRaw:
