... REV 1.1 10/6/00 X9410 DESCRIPTION The X9410 potentiometers (XDCP monolithic CMOS integrated microcircuit. The digitally controlled potentiometer is implemented using 63 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 address inputs are used to set the least significant 2 bits of the 8-bit slave address. A match in the slave address serial data stream must be made with the address input in order to initiate communication with the X9410. A maximum of 4 devices may occupy the SPI serial bus. Potentiometer Pins V ...

... Data Register zero (DR0) upon power-up. The Wiper Counter Register is a volatile register; that microcircuit is, its contents are lost when the X9410 is powered- down. Although the register is automatically loaded with the value in DR0 upon power-up, this may be different from the value present at power-down. ...

... WIP bit is read with a Read Status command. INSTRUCTIONS Identification (ID) Byte The first byte sent to the X9410 from the host, following a CS going HIGH to LOW, is called the Identification byte. The most significant four bits of the slave address are a device type identifier, for the X9410 this is fixed as 0101[B] (refer to Figure 2). The two least signifi ...

... Five instructions require a three-byte sequence to Pot Select complete. These instructions transfer data between the host and the X9410; either between the host and one of the data registers or directly between the host and the Wiper Counter Register. These instructions are: and R ...
