because this application does not use problematic constructions, like bit
fields in the source code.
In some places, using individual assembler instructions in the form of
in-line assembler directives is considered useful, for example, for the
interrupt enable in the main module U08MAIN.C. For this purpose, the
Cosmic C Compiler offers the following instruction:
_asm("<assembly statement >");
When using other compilers, similar instructions should be available.
However, some small syntactic adjustments can be necessary. Beside
the main module, the modules
such in-line assembler constructions.
The marking of a function as an interrupt service routine is not regulated
in the ANSI-C standard. For lack of a uniform regulation, the different
compilers handle this necessary marking in a different way. For
example, the Cosmic C Compiler uses the modification @interrupt:
@interrupt void interrupt_handler();
Other compilers use "#pragma" instructions to mark interrupt functions.
