Typical values are based on characterization data at V
This is the shortest pulse that is guaranteed to be recognized as a reset pin request.
To enter BDM mode following a POR, BKGD/MS should be held low during the power-up and for a hold time of t
rises above V
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.
Timing is shown with respect to 20% V
Except for LCD pins in Open Drain mode.
