C166: Disabling Interrupts in a Function

Information in this article applies to:

• C166 All Versions

QUESTION

How do I disable interrupts in a function?

ANSWER

Use #pragma disable to disable interrupts for the duration of a function. For example:

#pragma disable
void function (void)
{
if (flag == 0)
  {
  flag = 1;
  flag2 = 1;
  }
}

This disables interrupts on entry to function and restores interrupts when exiting.

MORE INFORMATION

• Refer to DISABLE in the C166 User's Guide.
