Compatibility of PWAKEUP of APB completer with Q-channel compliant clock controller

Hi,

What is the recommended way of connecting PWAKEUP of an APB completer with the Q-channel interface signals of a clock controller to ensure correct functionality.

Regards,

Hi Rishi,

You can connect PSEL to PWAKEUP if the upstream interface does not have a PWAKEUP signal. This will ensure that PWAKEUP meets the requirements of the APB Specification, and will deassert it there are no transfers being sent to the APB interface.
