12 description: |
13 The Timer/PWM Module (TPM) supports input capture, output compare,
14 and the generation of PWM signals to control electric motor and power
15 management applications. The counter, compare and capture registers
16 are clocked by an asynchronous clock that can remain enabled in low
17 power modes. TPM can support global counter bus where one TPM drives
18 the counter bus for the others, provided bit width is the same.
