5.3.5 Debug
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-KL25Z is the onboard OpenSDA circuit (see section 5.2).
However, an unpopulated 10-pin (0.05”) Cortex Debug connector, J6, provides access to the SWD
signals. The Samtec FTSH-105-02-F-D or compatible connectors can be added to the J6 through-hole
debug connector to allow for an external debug cable to be connected.

5.4 Capacitive Touch Slider
Two Touch Sense Input (TSI) signals, TSI0_CH9 and TSI0_CH10, are connected to capacitive electrodes
configured as a touch slider. Freescale’s Touch Sense Software (TSS) provides a software library for
implementing the capacitive touch slider.

5.5 3-axis Accelerometer
A Freescale MMA8451Q low-power, three-axis accelerometer is interfaced through an I
2
C bus and two
GPIO signals as shown in Table 4 below. By default, the I
2
C address is 0x1D (SA0 pulled high).
