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.
