9.5.7.3Power Manager PLL Configuration Register (PPCR)

The PPCR contains bits used to configure the core operating frequency generated by the PLL. The following table shows the bit-field definitions for this register. See Chapter 8, “Clocks” for the frequencies generated through settings in this register. Note that the contents of this register are preserved during sleep mode and do not need to be re-initialized after a wake-up event. The PPCR is only cleared upon the assertion of nRESET (hard reset).
