DESCRIPTION
The X9418 integrates two nonvolatile EEPOTs, digitally
controlled potentiometers, on a monolithic CMOS micro-
circuit.
The X9418 contains two 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 two wire 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 set the position of the wiper on
the resistor array. Power-up recalls the contents of data
register R0 to the Wiper Counter Register.
