... Device Address DEVICE OPERATION The CAT5259 is four resistor arrays integrated with a I²C serial interface logic, four 8-bit wiper control registers and sixteen 8-bit, non-volatile memory data registers. Each resistor array contains 255 separate resistive elements connected in series. The physical ends of each array are equivalent to the fixed terminals of a ...

... Four instructions require a two-byte sequence to complete, as illustrated in Figure 7. These instructions transfer data between the host/processor and the CAT5259; either between the host and one of the data registers or directly between the host and the Wiper Control Register. These instructions are: — XFR Data Register to Wiper Control Register ...
