A 7-bit wiper control register (WCR) independently controls the wiper tap switches for the DPP. Associated with the control register is a 7-bit nonvolatile memory data register (DR) used for storing the wiper settings. Changing the value of the wiper control register or storing that value into the nonvolatile memory is performed via a 3-input Increment-Decrement interface. The CAT5133 comes with 2 voltage supply inputs: Vcc (digital supply voltage) input and V+ (analog bias supply) input.
