Timer Pulse-Width Modulator (S08TPMV3)
14.1
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, TPM1CHn, where n is the channel number (for
example, 0–3). The TPM shares its I/O pins with general-purpose I/O port pins (refer to the
Connections
MC9S08EN32 Series MCUs have one TPM module, TPM1. In all available packages, TPM1 is 4-channel,
as shown in the following block diagram.

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
