TPM Module Timing
Synchronizer circuits determine the shortest input pulses that can be recognized or the fastest clock that
can be used as the optional external source to the timer counter. These synchronizers operate from the
current bus rate clock.

1 Typical values are based on characterization data at V
DD = 3.0 V, 25 °C unless otherwise stated.
2 This is the shortest pulse that is guaranteed to be recognized as a reset pin request. Shorter pulses are not guaranteed to
override reset requests from internal sources.
3 To enter BDM mode following a POR, BKGD/MS must be held low during the power-up and for a hold time of t
MSH after VDD
rises above VLVD.
4 This is the minimum pulse width that is guaranteed to pass through the pin synchronization circuitry. Shorter pulses may or
may not be recognized. In stop mode, the synchronizer is bypassed so shorter pulses can be recognized in that case.
5 Timing is shown with respect to 20% V
DD and 80% VDD levels. Temperature range –40 °C to 85 °C.
