The device contains configuration registers and programmable coefficients that can be set to the desired values for a specific system and application use. These registers are called device control registers and are each eight bits in width, mapped using a page scheme.
Each page contains 128 configuration registers. All device configuration registers are stored in page 0, which is the default page setting at power up (and after a software reset). Page 1 consists of the live status registers and input diagnostic successive-approximation register (SAR) data for advanced diagnostic purposes. All programmable coefficient registers are located in page 2, page 3, and page 4. The current page of the device can be switched to a new desired page by using the PAGE[7:0] bits located in register 0 of every page.
