The CPU pipeline clock speed is selected during cold reset by the boot configuration vector (see Table 2).
Ethernet clock (MIIRXCLKP and MIITXCLKP) frequency must be equal to or less than 1/2 CLKP frequency.
USB clock (USBCLKP) frequency must be less than CLKP frequency.
ATM Utopia clock (RXCLKP and TXCLKP) frequency must be equal to or less than 1/2 CLKP frequency.
