5.3.1 Clock Source
The Kinetis KL2 microcontrollers feature an on-chip oscillator compatible with three ranges of input crystal or resonator frequencies: 32-40 kHz (low freq. mode), 3-8 MHz (high freq. mode, low range) and 8-32 MHz (high freq. mode, high range). The KL25Z128 on the FRDM-KL25Z is clocked from an 8 MHz crystal.
5.3.2 USB Interface
The Kinetis KL2 microcontrollers feature a dual-role USB controller with on-chip full-speed and low- speed transceivers. The USB interface on the FRDM-KL25Z is configured as a full-speed USB device. J5 is the USB connector for this interface.
5.3.3 Serial Port
The primary serial port interface signals are PTA1 and PTA2. These signals are connected to both the OpenSDA and to the J1 I/O connector.
5.3.4 Reset
The PTA20/RESET signal on the KL25Z128 is connected externally to a pushbutton, SW1, and also to the OpenSDA circuit. The reset button can be used to force an external reset event in the target MCU. The reset button can also be used to force the OpenSDA circuit into bootloader mode. Please refer to section 5.2, Serial and Debug Adapter (OpenSDA), for more details.
5.3.5 Debug
controller of this interface on the FRDM-KL25Z is the onboard OpenSDA circuit (see section 5.2). debug connector to allow for an external debug cable to be connected.

5.8 Arduino Compatibility
The I/O headers on the FRDM-KL25Z are arranged to allow compatibility with peripheral boards (known as shields) that connect to Arduino™ and Arduino-compatible microcontroller boards. The outer rows of pins (the even numbered pins) on the headers share the same mechanical spacing and placement as the I/O headers on the Arduino Revision 3 (R3) standard.
FRDMKL25ZUM FRDM-KL25Z User's Manual Page 13 of 14 Refer to the FRDM-KL25Z Pinouts spreadsheet for a compatibility chart showing how all the functions of the KL25Z signals on the I/O connectors map to the pin functions available on the Arduino Uno R3.
