JUDGE mode and BCD mode
Output signals operate under either JUDGE mode or BCD mode. In BCD mode, signals are
used for both the upper and lower digits (and range information).
See: "Switching Output Modes (JUDGE Mode/ BCD Mode)" (p. 116)
Pin functions in JUDGE mode
Pin functions in BCD mode
The BCD upper digits and lower digits (and range information) are switched using the
BCD_LOW signal.
