Buzzer
IIC Pull-up
J16 - Accelerometer 3-axis Signals Connection Jumper ACC_EN
J19 - Buzzer enable jumper BUZ_EN
J20 - IIC Pullup Enable Jumpers IIC_EN
The DEMO9S08QE8 integrates a Piezo Transducer whose resonant
frequency is 4.0KHz. Jumper J19 connects to PTB5 to control this buzzer.
The DEMO9S08QE8 provides external pull-up resistors for SCL and SDA
lines, enabled by installing the corresponding jumpers on J20. By default both
jumpers are installed.

Figure 7-16: IIC External Pullup Enable IIC_EN (J20)
The accelerometer output signals are jumper settable to PTA7, PTA6,
PTC7, and PTA1. PTA6 and PTC7 share the same Y-axis signal. By
default, the Y-axis signal is connected to PTA6.
Enables Buzzer to be controlled by PTB5. This is the default setting.
Enables IIC external pullup. This is the default setting.
