Timer Pulse-Width Modulator (S08TPMV3)

NOTE

This chapter refers to S08TPM version 3, which applies to the 0M74K and

newer mask sets of this device. 3M05C and older mask set devices use

S08TPM version 2. If your device uses mask 3M05C or older, please refer

to Appendix B, “Timer Pulse-Width Modulator (TPMV2) on page 331 for

information pertaining to that module.

Introduction

The TPM is a one-to-eight-channel timer system which supports traditional input capture, output compare,

or edge-aligned PWM on each channel. A control bit allows the TPM to be conﬁgured such that all

channels may be used for center-aligned PWM functions. Timing functions are based on a 16-bit counter

with prescaler and modulo features to control frequency and range (period between overﬂows) of the time

reference. This timing system is ideally suited for a wide range of control applications, and the

center-aligned PWM capability extends the ﬁeld of application to motor control in small appliances.

The TPM uses one input/output (I/O) pin per channel, TPMxCHn, where x is the TPM number (for

example, 1 or 2) and n is the channel number (for example, 0–5). The TPM shares its I/O pins with

general-purpose I/O port pins (refer to the Pins and Connections chapter for more information).

MC9S08DN60 Series MCUs have two TPM modules. In all packages, TPM2 is 2-channel. The number

of channels available on external pins in TPM1 depends on the package:

•

Six channels in 64-pin and 48-pin packages

•

Four channels in 32-pin packages.
