2.1.9
RESET is a dedicated pin with a pull-up device built in. This pin is connected to the 6-pin BDM connector,
therefore a development system can directly reset the MCU system. The reset switch (SW10) is active low
and provides a way to apply a reset to the MCU. The reset switch is connected directly to the RESET signal
of the MC9S08LG32 MCU. A 5.1 kΩ pull-up resistor to V
operation preventing spurious reset detections. When the reset switch is pressed the RESET signal is
grounded, and the MCU recognizes a reset.
2.1.10
TSSEVB includes two detachable overlays provided by KEE Group. These overlays have an adhesive that
can be used to place the overlay over the electrodes. These overlays can be used to test different dielectric
constants placed over the electrodes. The overlays can be placed, and removed many times while retaining
adherence.
