*
* This module contains the function `__low_level_init', a function
* that is called before the `main' function of the program. Normally
* low-level initializations - such as setting the prefered interrupt
* level or setting the watchdog - can be performed here.
*
* Note that this function is called before the data segments are
* initialized, this means that this function cannot rely on the
* values of global or static variables.
*
* When this function returns zero, the startup code will inhibit the
* initialization of the data segments. The result is faster startup,
* the drawback is that neither global nor static data will be
* initialized.
