The Low Power Stop mode will be activated if software writes PRCM.CM_CLKMODE_DPLL_PCIE_REF[2:0] DPLL_EN bit field to 0x1. The module enters a low Power Stop mode by gating all its internal clocks (REFCLK) and powering down internal LDO and DCO. CLKOUTLDO remains gated (low) during this mode.
When the DPLL_PCIE_REF is in Low Power Stop mode, the input clock on CLKINP pin is not needed.
