DESCRIPTION
The X9400 integrates four nonvolatile (EEPOTs), digitally
controlled potentiometers, on a monolithic CMOS
microcircuit.
The X9400 contains four resistor arrays, each composed
of 63 resistive elements. Between each element and at
either end are tap points accessible to the wiper
elements. The position of the wiper element on the array
is controlled by the user through the SPI serial bus
interface.
Each resistor array has associated with it a Wiper
Counter Register and four 6 bit data registers that can be
directly written and read by the user. The contents of the
Wiper Counter Register controls the position of the wiper
on the resistor array. Power-up recalls the contents of
data register R0 to the Wiper Counter Register.
