Digital Output Characteristics (OROUT, STATUS)
Digital Input Characteristics (OROUT_IN, STATUS_IN)
If the ATA6871 is configured as first IC (master) in a string (CHIPONE = 1, CHIPLAST = 0 or 1),
the output OROUT acts as a push-pull output, the output STATUS as an open drain output. If
the ATA6871 is configured to be a stacked IC (CHIPONE = 0, CHIPLAST = 0 or 1), the output
signals STATUS and OROUT coming from the upper IC need to be transferred to the STATUS
and OROUT output of the master in the string via the STATUS_IN and OROUT_IN inputs. In this
case the OROUT and STATUS outputs act as level shifters based on current sources.
