Description

0

Det

Signals a valid detection.

0: no detection

1: valid detection

1

Dir

Signals the direction of the detection.

0: backward/receding movement detected

1: forward/approaching movement detected

Only valid if Bit 0 is high.

2

Range

Signals the speed range of the detection depen-

ding on the speed threshold parameter D06.

0: low speed range detected

1: high speed range detected

Only valid if the speed range threshold

is > 0 and if Bit 0 is high.
