This section identifies the operating modes supported by the APLL and the control bit fields to set its operating modes.
In order to disable the APLL_PCIE, the user needs to disable PCIe_SSx (where x = 1 or 2) using the CM_PCIE_PCIESSx_CLKCTRL[1:0] MODULEMODE registers. When PCIe_SS is disabled, the PRCM module automatically disables the APLL_PCIE. Please note that setting CM_CLKMODE_APLL_PCIE[1:0] MODE_SELECT bitfield to 0x0 does not disable the APLL_PCIE.
Table 3-105 lists the operating modes supported by the DPLL.
