Is it enough for the system clock controller to only monitor csysack of PL340 to know whether PL340 has acknowledged the low power request on csysreq?

Applies to: PL340 AXI SDRAM Controller

Answer

Yes. cactive will always go low before csysack is asserted, so it is enough to only monitor csysack in this case.
