Notational Conventions

This document uses the following conventions.

  • Hexadecimal numbers may be shown with the suffix h or the prefix 0x. For example, the following number is 40 hexadecimal (decimal 64): 40h or 0x40.
  • 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 with default reset value below. A legend explains the notation used for the properties.
    • Reserved bits in a register figure can have one of multiple meanings:
      • Not implemented on the device
      • Reserved for future device expansion
      • Reserved for TI testing
      • Reserved configurations of the device that are not supported
    • Writing nondefault values to the Reserved bits could cause unexpected behavior and should be avoided.
