About This Manual
This document describes the operation of the high-resolution extension to the pulse width modulator
(HRPWM) . The HRPWM module described in this reference guide is a Type 0 HRPWM. See the
TMS320x28xx, 28xxx DSP Peripheral Reference Guide (SPRU566) for a list of all devices with an
HRPWM module of the same type, to determine the differences between types, and for a list of
device-specific differences within a type.
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.
