The R5FSS has four clock inputs:
CPU0_CLK and CPU1_CLK are the clocks for all of the internal CPU logic, while CPU0_ICLK and CPU1_ICLK are the clocks for all of the interfaces for their associated CPU (for example: VBUSM and VBUSP bridges, exception generation, debug and trace logic). CPU1 clocks are automatically gated in single-core mode.
The interface clock is an integer ratio of the CPU clock. The exact ratio for this device is 1:1.
