6.14. Oscillator Sources
All crystals are provided by Epson Electronics America. A crystal is fitted on the RDK and used to supply the main clock to the Renesas
microcontroller. Table 6-11 details the crystals that are fitted on the RX62N RDK.

6.15. Reset Circuit
The RDK includes a user reset switch which to reset both the RX62N MCU and Debugger MCU. This is connected to the internal reset circuit on
the RX62N (RES#) and reset input on the Segger J-Link Debugger (TRESin). The Segger MCU can also control this pin via its TRESout pin for
debugging purposes.
There is a peripheral reset control line connected to PC2 (pin 49) on the RX62N which can be used to reset major peripherals at once. This
includes the Ethernet PHY, Beagle Port, Application Header, and Debug LCD.
6.16.Total Phase Beagle Debug Header
The Beagle I2C/SPI Protocol Analyzer is a non-intrusive USB-based bus monitor that can capture, display, and filter I2C and SPI data as it
appears on the bus. Using both the Data Center Software and Beagle analyzer, users can easily view I2C bus traffic (up to 4 MHz) and SPI bus
traffic (up to 24 MHz) in real time. Additional functionality allows engineers to filter data against a wide variety of parameters, or instantly search
for specific hexadecimal or ASCII data patterns during a live capture. The Beagle analyzer is fully supported on Windows, Linux, and Mac OS X,
and comes with free software, free APIs, free technical support, and free software/firmware upgrades.
Total Phase manufactures powerful and affordable USB, I2C, SPI, and CAN tools for embedded systems engineers. The complete line of Total
Phase host adapters and protocol analyzers are the development and debugging tools of choice for Fortune 500 companies, small businesses,
and research institutions all over the world.
