■Equivalent circuit
-Output The signal output circuit is operated through a TTL open collector.
-Input
■Signal timing
-STAB This signal turns on at the same time as BCD data when stability is detected by Motion
Detect (MD). This signal is not output when the output data is a real time
value.("Motion Detect (MD)"on page 41)
-OVER This signal is output at the time of a sensor error or ±OVER.
