    shared wakeup interrupt gpio


      I'm working on a custom board design where there will be no SW2 to provide a wakeup interrupt. I would like to use an external signal from a rotational pulse sensor (used for calculating RPM) to provide a wakeup signal. Can I just tie this signal into the current pin used for SW2 and still be able to calculate RPM or do I need to chain 2 IRQ blocks together? Will there be any problems with a constant triggering of the wakeup IRQ because this is also a RPM signal? 


      This is my 1st PSoC 4 BLE project so any other helpful hints would be welcome.
