REQ

Request to change the Watchdog time (T

RANGE_SEL REQ1

Selection of the integration time and the representation of
measured frequency value.

RANGE_SEL REQ0

Selection of the integration time and the representation of
measured frequency value.

This constant must be set to zero.

RANGE_SEL ACK1 Acknowledgment to Range Selection, Frequency values are valid.

RANGE_SEL ACK0 Acknowledgment to Range Selection, Frequency values are valid.

This value is not evaluated.

With the control and status byte the following tasks are possible:

Setting the Method of Measuring, Frequency Range and Representation:

The method of measuring and the representation depends on the
RANGE_SEL REQ bits in the CONTROL byte. Dependent on the adjusted
measuring method also the maximum frequency range changes.
The following table illustrates the different modes.
