5.3.7 Capacitive touch slider
Two general purpose I/Os (with interrupt functionality), PTA12 and PTA13, can be connected to capacitive
electrodes configured as a touch slider via 0R resistors. Because the TSI module is not included on the
KL43, this functionality was not primary. Freescale’s Touch Sense Software (TSS) provides a software
library for implementing the capacitive touch slider using GPIO method.
5.3.8 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).
5.3.9 Three-axis digital magnetometer
Note: for board revision SPF-28062_C1 and later, the MAG3110 is no longer available and is not present
on the board.
A Freescale MAG3110 three-axis digital magnetometer
is interfaced through an I
2
C bus and one GPIO
signal, as shown in Table 6 below. The I
2
C address is 0x1E.
