Figure 5. Infrared Port Implementation
Note: The PTC5 pin is shared between the Infrared circuit and the green LED (D50). Jumper J1 routes
the signal to either the infrared (shunt on pin 2-3) or LED (shunt on 1-2).
2.6 Accelerometer
An MMA8451Q digital accelerometer is connected to the MCF51JF MCU through an I2C interface (I2C0,
PTC6 and PTC7) and two GPIO/IRQ signals (PTD0 and PTD1).
Figure 6. Accelerometer Circuit
2.7 Potentiometer, Pushbuttons, LEDs
The TWR-MCF51JF features one pushbutton switch (SW1) connected to the IRQ signal (PTB0), one
pushbutton switch (SW2) connected to the master reset signal (PTC1), two capacitive touch pad
electrodes connected to TSI0_CH10 (PTB1) and TSI0_CH9 (PTE1), two user-controllable LEDs—one
green and one orange—connected to GPIO signals (PTC5 and PTA0), and a potentiometer connected to
an ADC input signal (ADC0_SE12, PTD5). Refer to Table 4 “I/O Connectors and Pin Usage Table” for
more information.
2.8 Microphone
A microphone circuit is provided allowing for sampling of audio data. A single-ended ADC signal
(ADC0_SE11, PTD4) is used to sample the value on the microphone IC output. A jumper, J5, is provided
to isolate the ADC signal from the microphone so that it can be used for other purposes (refer to Table
4 “I/O Connectors and Pin Usage Table” for more information).
