System Overview
— To supply power to the board from the OSBDM, place the J4 jumper on the 1–2 positions.
— To supply power to the board from the MC9S08JM60 Comm MCU, place the jumper on the
2–3 positions.

2.1.5
To supply power to the TSSEVB externally, plug the voltage converter included in the TSSEVB
kit to the board's barrel connector. When using the external power supply, the voltage from the
USB_BDM is automatically disconnected from the board. Refer to section Section 2.3, “Header
and Jumper Connections ,” for more information about how to configure the jumpers.
Buzzer
TSSEVB provides a piezoelectric speaker connected to the PTA6 pin of the MC9S08LG32
microcontroller. This speaker can be easily used with any touch sensing application.
2.1.6
Clock
TSSEVB uses the Internal Clock Source (ICS) of MC9S08LG32 to provide timing to the board. The ICS
module contains a Frequency-Locked Loop (FLL) to increase the bus frequency using the internal clock
as reference. For more information on the ICS module, refer to the MC9S08LG32 Reference Manual
(document MC9S08LG32RM).
2.1.7
LCD
TSSEVB provides a custom LCD with special segments that can be used to represent each of the electrodes
featured in the board. Depending on the application, these segments can change their functionality. When
running the application demo, the LCD allows you to visualize the performance of the electrodes working
along with the TSS. You can use the application demo code provided with the TSSEVB documentation as
a guideline to configure and use the LCD on any application. The LCD can display up to 4 characters
besides the special segments.
2.1.8
TSSEVB Electrodes
The TSSEVB provides all the decoding structures supported by the Touch Sensing Software, and also
provides some special electrodes. The TSSEVB features the following electrodes structures.
? Rotary structure formed by 8 electrodes plus one electrode in the middle of the structure.
? Slider structure formed by 8 electrodes.
? Keyboard structure formed by 6 electrodes.
? 4 electrodes with an LED in the middle.
? 4 multiplexed electrodes.
? 4 electrodes of different sizes for user evaluation.
