    DESCRIPTION
    The X9111 integrates a single digitally controlled
    potentiometer (XDCP) on a monolithic CMOS
    integrated circuit.
    The digital controlled potentiometer is implemented
    using 1023 resistive elements in a series array.
    Between each element are tap points connected to the
    wiper terminal through switches. The position of the
    wiper on the array is controlled by the user through the
    SPI bus interface. The potentiometer has associated
    with it a volatile Wiper Counter Register (WCR) and
    four non-volatile Data Registers that can be directly
    written to and read by the user. The contents of the
    WCR controls the position of the wiper on the resistor
    array though the switches. Powerup recalls the
    contents of the default data register (DR0) to the WCR.
    The XDCP can be used as a three-terminal
    potentiometer or as a two terminal variable resistor in
    a wide variety of applications including control,
    parameter adjustments, and signal processing.
