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 provides an easy method for swapping
the device between 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.
