IIC Pull-up
Analog Input Potentiometer
Optional External Crystal Circuitry Jumper Enable
J19 - Buzzer enable jumper BUZ_EN
J20 - IIC Pullup Enable Jumpers IIC_EN
J21 - Potentiometer Output Selection Jumpers POT_EN

The MC9S08QB8 does not have a dedicated IIC module. Installing IIC_EN
jumpers has no effect on the device.
The DEMO9S08QB8 provides an easy access 10Kohm potentiometer whose
output may be connected to PTC6 and/or PTA0, selectable by J21, POT_EN.
The DEMO9S08QB8 provides external crystal circuitry without components
populated. A user may elect to populate the components, and may use
jumper J17, CLOCK_EN, to enable the external crystal circuitry.

Figure 7-16: IIC External Pullup Enable IIC_EN (J20)
Enables Buzzer to be controlled by PTB5. This is the default setting.
Enables IIC external pullup. This is the default setting.
Selects the potentiometer output connection. By default it is
connected to PTA0.
