Output Logic Setting

This sets the logic for the BCD data, sign, and READY signal that are output. Each can be set independently. However, when
using 3-state output and high-speed output, use negative logic for the READY signal. If positive logic is used, the signal will
always be high (OFF), making it impossible to confirm when the signal is valid.
• BCD data logic (identical for each bit)
If positive logic is used:
• Sign bit logic
If positive logic is used:
• READY signal logic
If positive logic is used:
Note Output signals are all open collector output. Therefore, when nothing is connected to the outputs, output signal ON/OFF
can be confirmed but the logic level H/L cannot. If a pull-up resistor is connected to each output pin, L level output can be
detected when the output signal is ON, and H level output when OFF.
