title: NXP Low Power Timer/Pulse Width Modulation Module (TPM)
maintainers:
- Dong Aisheng <aisheng.dong@nxp.com>
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.
