31.3.2 Register Descriptions
This section consists of register descriptions in address order. Each description includes a standard register
diagram with an associated figure number. Writes to a reserved register location do not have any effect and
reads of these locations return a 0. Details of register bit and field function follow the register diagrams,
in bit order.
