DISABLE Compiler Directive

The DISABLE directive instructs the compiler to generate code that disables all interrupts for the duration of a function. This directive must be specified with #pragma immediately before the function declaration. The DISABLE directive applies to one function only and must be re-specified for each new function.

Note

• The DISABLE directive must be specified using #pragma only and may not be specified on the command line.
• The DISABLE directive may be specified more than once in a source file but must be specified for each function that is to execute with interrupts disabled.
• A function with disabled interrupts may not have a return type of bit.
