5.2.2 AMC7812EVM Low-Level Configuration Page
The AMC7812EVM features a register map page that allows access to low-level communication by
directly writing to and reading from the AMC7812 registers. Selecting a register on the
Register Map list
presents a description of the values in that register and also displays information such as the register’s
address, default value, size, and current value. The register values can be modified through the Hex
Write
Register field, or set through Boolean checkboxes in the Register Data column, as displayed in Figure 11 .

can be accessed through the Load Config button.
