Calls a user routine at startup to perform important initialization functions such as setting ports.








This directive will call a label named _INIT_MICRO just after the most important initialization is performed. You can put the _INIT_MICRO routine into your program, or you can put it in a library. Advantage of a library is that it is the same for all programs, and advantage of storing the code into your program is that you can change it for every program.


It is important that you end the routine with a RETURN as the label is called and expects a return.

The $initmicro can be used to set a port direction or value as it performs before the memory is cleared which can take some mS.

The best solution for a defined logic level at startup remains the usage of pull up/pull down resistors.
