9-1-5. Polarity output (MUNUS)
This signal indicates the polarity of the BCD data.
0: positive (+), 1: minus (-)
9-1-6. Over status output (OVER)
This signal outputs 1 when one of the following conditions occurs in the BCD data.
9-1-7. Data strobe (STROBE)
BCD data is updated every time an A/D conversion takes place, and a strobe pulse is
output in synchronization with the conversion. Use rising edges to read in the BCD
data.
9-1-8. Hold input
Shorting this input to COM terminal holds the BCD output. The strobe pulses are also
suppressed.
9-1-9. Logic toggling input
This input toggles the signal logic between positive and negative.
Open: negative logic
Close: positive logic
