Asynchronous reset input (active LOW). Resets registers and
disables VREF data and clock differential-input receivers.
Chip select inputs (active LOW). Disables data outputs
switching when both inputs are HIGH.
Data inputs. Clocked in on the crossing of the rising edge of
CK and the falling edge of CK.
The outputs of this register will not be suspended by DCS and
CSR control.

Not connected. Ball present but no internal connection to the
die.
Do-not-use. Ball internally connected to the die which should
be left open-circuit.
