6.7. Oscillator Sources
A crystal oscillator is fitted on the CPU board and used to supply the main clock input to the Renesas microcontroller.
oscillators that are fitted and alternative footprints provided on this CPU board:
Warning: When replacing the default oscillator with that of another frequency, the debugging monitor will not function unless the following
are corrected:
6.8. Reset Circuit
The CPU Board includes a simple latch circuit that links the mode selection and reset circuit. 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 (SW1) on pressing the reset button. This control is subsequently used to
modify a port pin state to select which code is executed.
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.
