title: NXP Low Power Timer/Pulse Width Modulation Module (TPM)

description: |
  The Timer/PWM Module (TPM) 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. TPM can support global counter bus where one TPM drives
  the counter bus for the others, provided bit width is the same.
