FEATURES
The DEMO908LB8 is an evaluation or demonstration board for the Freescale 68HC908LB8
microcontroller. Application development is quick and easy with the included DB9 serial cable,
sample software tools, and examples. A MON08 port is provided for development tool
application support and is compatible with HC08 monitor interface cables and software.
Debug monitor access is also supported through the DEBUG Port. A 28-pin MCU I/O
connector (J1) allows interfacing the DEMO908LB8 board to an external development
environment or external test equipment.
