About This Manual

This document provides an overview of the 64-bit timer in the TMS320TCI648x/TMS320C6472 DSP. The

timer can be configured as a general-purpose 64-bit timer, dual general-purpose 32-bit timers, or a

watchdog timer. When configured as dual 32-bit timers, each half can operate in conjunction (chain mode)

or independently (unchained mode) of each other.

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.
