Electrical Characteristics
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
above V
This is the minimum pulse width that is guaranteed to be recognized as a keyboard interrupt request in stop mode.
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.
Timing is shown with respect to 20% V
2.14.2
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 FTM timer counter. These synchronizers operate from the current ICSOUT clock. The ICSOUT
clock period = 0.5 × t
