The CPU pipeline clock (PCLK) speed is selected during cold reset by the boot configuration vector (see Table 3). Refer to Chapter 3, Clocking and Initialization, in the RC32434
The ethernet clock (MIIxRXCLK and MIIxTXCLK) frequency must be equal to or less than 1/2 ICLK (MIIxRXCLK and MIIxTXCLK <= 1/2(ICLK)).
PCICLK must be equal to or less than two times ICLK (PCICLK <= 2(ICLK)) with a maximum PCICLK of 66 MHz.
The input clock (CLK) is input from the external oscillator to the internal PLL.
ICLK is the internal IPBus clock. It is always equal to PCLK divided by 2. This clock cannot be sampled externally.
User Reference Manual for the allowable frequency ranges of CLK and PCLK.
