The sole debug interface on all Kinetis L Series devices is a Serial Wire Debug (SWD) port. The primary controller of this interface on the FRDM-KL46Z is the onboard OpenSDA circuit (see section 5.2). However, an unpopulated 10-pin (0.05”) Cortex Debug connector, J11, provides access to the SWD signals. The Samtec FTSH-105-02-F-D or compatible connectors can be added to the J11 through-hole debug connector to allow for an external debug cable to be connected.

Note that all pinout data is available in spreadsheet format in FRDM-KL46Z Pinouts. See the Reference Documents section for details. 5.1.15 Arduino Compatibility The I/O headers on the FRDM-KL46Z 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.
