Note: Many of the trace signals connected to the debug connector are also connected elsewhere on
the TWR-K60N512. Refer to Table 6 “I/O Connectors and Pin Usage Table” and Table 7 “TWR-K60N512
Primary Connector Pinout” for more information.
2.5 Infrared Port
An infrared transmit and receive interface is implemented as shown in Figure 5 below. The CMT_IRO
pin directly drives an infrared diode. The receiver uses an infrared phototransistor connected to an on-
chip analog comparator through a low-pass filter. Internal to the K60 device, the output of the analog
comparator can be routed to a UART module for easier processing of the incoming data stream.
2.6 Accelerometer
An MMA7660 digital accelerometer is connected to the K60 MCU through an I2C interface and a
GPIO/IRQ signal. Refer to Table 6 “I/O Connectors and Pin Usage Table” for connection details.
2.7 Potentiometer, Pushbuttons, LEDs
The TWR-K60N512 features two pushbutton switches connected to GPIO/interrupt signals, one
pushbutton connected to the master reset signal, four capacitive touch pad electrodes, four user-
controllable LEDs, and a potentiometer connected to an ADC input signal. Refer to Table 6 “I/O
Connectors and Pin Usage Table” for information about which port pins are connected to these
features.
2.8 General Purpose Tower Plug-in (TWRPI) Socket
The TWR-K60N512 features a socket that can accept a variety of different Tower Plug-in modules
featuring sensors, RF transceivers, and more. The General Purpose TWRPI socket provides access to
