  DESCRIPTION
  The X9Cxxx are Intersil digitally controlled (XDCP)
  potentiometers. The device consists of a resistor
  array, wiper switches, a control section, and nonvola-
  tile memory. The wiper position is controlled by a
  three-wire interface.
  The potentiometer is implemented by a resistor array
  composed of 99 resistive elements and a wiper switch-
  ing network. Between each element and at either end
  are tap points accessible to the wiper terminal. The
  position of the wiper element is controlled by the CS,
  U/D, and INC inputs. The position of the wiper can be
  stored in nonvolatile memory and then be recalled
  upon a subsequent power-up operation.
  The device can be used as a three-terminal potentiom-
  eter or as a two-terminal variable resistor in a wide
  variety of applications including:
  – control
  – parameter adjustments
  – signal processing
