About This Manual
This document describes the DDR2 memory controller in the TMS320C642x Digital Signal Processor (DSP).
Notational Conventions
This document uses the following conventions.
∙Hexadecimal numbers are shown with the suffix h. For example, the following number is 40 hexadecimal (decimal 64): 40h.
∙Registers in this document are shown in figures and described in tables.
–Each register figure shows a rectangle divided into fields that represent the fields of the register. Each field is labeled with its bit name, its beginning and ending bit numbers above, and its read/write properties below. A legend explains the notation used for the properties.
–Reserved bits in a register figure designate a bit that is used for future device expansion.
