Timer/PWM Module (TPM)
46.1 Introduction
The TPM (Timer/PWM Module) is a 2- to 8-channel timer which supports input capture,
output compare, and the generation of PWM signals to control electric motor and power
management applications.
The counter, compare and capture registers are clocked by an asynchronous clock that
can remain enabled in low power modes. An example of using the TPM with the
asynchronous DMA is described in
AN4631:Using the Asynchronous DMA features of
the Kinetis L Series .
46.1.1 TPM Philosophy
The TPM is built upon a very simple timer (HCS08 Timer PWM Module – TPM) used
for many years on NXP's 8-bit microcontrollers. The TPM extends the functionality to
support operation in low power modes by clocking the counter, compare and capture
registers from an asynchronous clock that can remain functional in low power modes.
46.1.2 Features
The TPM features include:
• TPM clock mode is selectable
• Can increment on every edge of the asynchronous counter clock
• Can increment on rising edge of an external clock input synchronized to the
asynchronous counter clock
• Prescaler divide-by 1, 2, 4, 8, 16, 32, 64, or 128
