I am considering using the Blackfin SDP Controller Board and after review of the schematic, I am trying to understand the purpose of the EXT-WAKE0 signal which controls VDDINT and 3.3V_Sleep. Can anyone help?
Thank you in advance,
I spoke with our Hardware Team who advised that this signal was added so that an extender board would be able to wake up the processor. As many of our processors are for low power space, it was decided that supporting various low power and sleep modes is important, hence providing this signal.
You can leave this signal unconnected, if you don't have a requirement for a wake-up signal.
