The internal voltage regulator (
WK input pin is a bi-level sensitive input. This means that both transitions, HIGH to LOW and LOW to HIGH, result
in a wake-up. The filtering time is
case of reverse polarity, no special protection must be set if the absolute maximum rating is respected. When the
SBC is below the minimum
ignored.
The state of the WK pin (low or high) can always be read in Normal Mode, Stop Mode and SW Flash Mode at the
bit WK State. When setting the bit “WK PIN on/off” to 1, the device wakes up from Sleep Mode with a high to low
or low to high transition. From Fail-Safe Mode the device will always go to Restart Mode with a high to low or low
to high transition. If the bit “WK PIN on/off” is set to 1 in Normal, Stop or SBC SW Flash Mode the interrupt bits
“WK 0 WK pin” and/or “WK 1 WK pin” are set in case of a change on the WK pin and an interrupt is generated if
not masked. With the bits “WK 0 WK pin” and “WK 1 WK pin” the interrupt for low to high transition and high to low
transition can be masked separately.
