DI, EI
Synopsis
Description
The di() macro disables all interrupts globally (regardless of priority settings), ei() re-enables inter-
rupts globally. These are implemented as macros defined in PIC18.h. The example shows the use
of ei() and di() around access to a long variable that is modified during an interrupt. If this was not
done, it would be possible to return an incorrect value, if the interrupt occurred between accesses to
successive words of the count value.
Example
192
#include <htc.h>
void ei (void)
void di (void)
#include <htc.h>
long count;
void
interrupt tick (void)
{
}
long
getticks (void)
{
count++;
long val;
di();
val = count;
ei();
return val;
/* Disable interrupts around access
to count, to ensure consistency.*/
