About This Manual
This Technical Reference Manual (TRM) details the integration, the environment, the functional
description, and the programming models for each peripheral and subsystem in the device.
The TRM should not be considered a substitute for the data manual, rather a companion guide that should
be used alongside the device-specific data manual to understand the details to program the device. The
primary purpose of the TRM is to abstract the programming details of the device from the data manual.
This allows the data manual to outline the high-level features of the device without unnecessary
information about register descriptions or programming models.
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.
