I want to use the Stop mode of CYBLE-012011-00 in my project.
I know that only the pins XRES and WAKEUP (P2[2] for CYBLE-012011-00) can be used to wakeup the device from stop mode.
The question is whether if an external pull-up resistor is required on the WAKEUP pin.
I do have an example project that seems to work with a switch attached to P2[2], P2[2] set as resistive pull up and the polarity of the wakeup pin set to active low, but I just want to check before I design my custom PCB.
Thank you.

AN86233 tells, that all GPIO settings and states will be frozen. Thus would mean that the internal pullup and state = high will be maintained during stop mode.

Thank you for the confirmation.
I have one more question.
I know that PSoC 4 and PRoC are different devices with different functionalities. But sometimes, I cannot seem to find the exact documentation for PRoC devices, e.g. System Reference Guides in PSoC Creator only point to documentation for PSoC 3/4/5LP devices. In these cases, can I resort to documentation for PSoC 4s?
I have just started to work with these devices and it is a little confusing yet.

In Creator, Workspace Explorer window (left hand side) there is a tab named Datasheets. There you will find a link to your selected device datasheet.
