when using an external reference at the REF pin.
REFADJ

Reference Buffer Output / ADC Reference Input. In internal reference mode, the reference buffer provides a
4.096V nominal output, externally adjustable at REFADJ . In external reference mode, disable the internal
buffer by pulling REFADJ to V

Three-State Digital I/O. D2 output (HBEN = low), D10 output (HBEN = high).
Three-State Digital I/O. D1 output (HBEN = low), D9 output (HBEN = high).
Three-State Digital I/O. D0 output (HBEN = low), D8 output (HBEN = high). D0 = LSB.

Used to multiplex the 12-bit conversion result. When high, the 4 MSBs are multiplexed on the data bus;
when low, the 8 LSBs are available on the bus.

When CS is low, in the internal acquisition mode, a rising edge on WRlatches in configuration data and starts an
acquisition plus a conversion cycle. When CS is low, in the external acquisition mode, the first rising edge on
WR starts an acquisition and a second rising edge on WR ends acquisition and starts a conversion cycle.

Clock Input. In external clock mode, drive CLK with a TTL/CMOS compatible clock. In internal clock mode,
place a capacitor (C
