5.1.9 Capacitive Touch Slider
Two Touch Sense Input (TSI) signals, TSI0_CH9/PTB16, and TSI0_CH10/PTB17 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.

5.1.10 Three-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 5 below. By default, the I
2
C address is 0x1D (SA0 pulled high).
