/**

    @file blinker.c

    @brief LED blinker demo for light52 core.

    Does nothing but send a greeting string to the console and do a binary count

    on port P0.

    Should fit in 4K of ROM and use no XRAM.

    This demo may come in handy to try the core on boards with no RS232 port or

    display.
