Timer/PWM Module (TPM)
19.1
Introduction
The TPM is a one-to-eight-channel timer system that supports traditional input capture, output compare,
or edge-aligned PWM on each channel. A control bit configures the TPM so all channels are 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.
NOTE
•
Use pin mux control registers from
Section 2.3, “Pin Mux Controls
” to
assign TPM signals to the MCF51CN128 package pins.
•
Most pin functions default to GPIO and must be software configured
before using TPM.
