MZT[1:0]

Input Termination Mode Select—Selects the termination mode used for all terminated inputs. Must be tied

High or Low.

MZT[1:0] = 00: disabled.

MZT[1:0] = 01: RT/2 Thevenin-equivalent (pull-up = RT, pull-down = RT).

MZT[1:0] = 10: RT Thevenin-equivalent (pull-up = 2*RT, pull-down = 2*RT).

MZT[1:0] = 11: reserved.

Input

PZT[1:0]

Input Termination Configuration Select—Selects which inputs are terminated. Must be tied High or Low.

PZT[1:0] = 00: Write Data only.

PZT[1:0] = 01: Write Data, Input Clocks.

PZT[1:0] = 10: Write Data, Address, Control.

PZT[1:0] = 11: Write Data, Address, Control, Input Clocks.

MCL

Input

NC

No Connect—There is no internal chip connection to these pins. They may be left unconnected, or tied High

or Low.

—

Not Used, Input—There is an internal chip connection to these input pins, but they are unused by the

device. They are pulled Low internally. They may be left unconnected or tied Low. They should not be tied

High.

Input

Not Used, Output—There is an internal chip connection to these output pins, but they are unused by the

device. Unused output pins are tri-stated internally. They should be left unconnected.
