E.2.3. Configuration Type C

System Clock obtains a free running clock. Port 0 gets a free running reference clock.

Port 0 is required to support CVP_INIT and CVP_UPDATE so that Port 0’s perst must be set to pin_perst_n.

Port 1 gets the RefClk from the Host where the RefClk is power gateable. This clock turns off when PERST# is asserted and it will be stable prior to PERST# deassertion.
