    Consult the target device RM for details on LVD operation. TIMING The TWR-S08 uses the MC9S08LL or MC9S08LH internal timing source by default. external 32 kHz XTAL oscillator, configured for low-power operation, is also provided. Consult the target device RM for details on configuring the selected timing source.

    ● ● ● The TWR-S08 applies a GD-5306P, 2x28 chip-on-glass, LCD connected directly to the target MCU. The target MCU provides the internal charge-pump and regulated LCD reference voltage required by the LCD. LCD contrast is trimmable under MCU control. Refer to the target device RM for further details on configuring using the LCD interface.

    G U I D E ACCELEROMETER The TWR-S08 applies the MMA7361L, 3-axis, analog accelerometer for tilt and motion-sense applications. The accelerometer supports 2 user selectable sensitivities - 1.5g / 6g. The SLEEP* input allows the device to be placed in a low-power mode. Separate X-, Y-, and Z- axis readings are routed to the MCU.

    Rev B boards. EDGE CONNECTOR PIN-OUT The TWR-S08 board connects to the Freescale Tower System using the 2 PCIe Edge Connectors. Note that according to the PCIe specification, the Bx signals are located on the top of the board and the Ax signals are located on bottom. Pin B1 for the primary and secondary connectors are at opposite ends of the board.
