6.7.Oscillator Sources
A crystal oscillator or ceramic resonator is fitted on the RSK and used to supply the main clock input to the Renesas microcontroller.

6.8.Reset Circuit
The CPU Board includes a simple latch circuit that links the mode selection and reset circuit. This provides an easy method for swapping
the device between Boot Mode, User Boot Mode and User mode. This circuit is not required on customers boards as it is intended for
providing easy evaluation of the operating modes of the device on the RSK. Please refer to the hardware manual for more information
on the requirements of the reset circuit.
The Reset circuit operates by latching the state of the boot switch on pressing the reset button. This control is subsequently used to
modify the mode pin states as required.
The mode pins should change state only while the reset signal is active to avoid possible device damage.
The reset is held in the active state for a fixed period by a pair of resistors and a capacitor. Please check the reset requirements carefully
to ensure the reset circuit on the user’s board meets all the reset timing requirements.
