Is it possible to wakeup the DA14580 by an external GPIO from Extended Sleep Mode in less than 10 us ?
In the new Software Release Notes 3.0.4 there is a reference to the application note AN-B-026:
"DA14580 wakeup mechanism using an external GPIO (ie CTS or SPI EN). More information is given in AN-B-026"
Perhaps this application note will answer my question - but I could not find it.
