... REV 1.1.4 10/11/02 X9400 DESCRIPTION The X9400 integrates potentiometers (XDCPs monolithic CMOS integrated circuit. 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 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 X9400. 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 is, its contents are lost when the X9400 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 X9400 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 X9400 this is fixed as 0101[B] (refer to Figure 2). The two least signifi ...

... P0 Five instructions require a three-byte sequence to complete. These instructions transfer data between the Pot Select host and the X9400; 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 ) select one ...
