Note 1. The ICLK and PCLKA frequencies must be the same and at least 12.5 MHz if the Ethernet controller is in use
Note 2. The PCLKB must run at a frequency of at least 24 MHz if the USB is in use.
Note 3. The FCLK must run at a frequency of at least 4 MHz when changing the ROM or E2 DataFlash memory contents.
