Example 2: assume initial level=High, PC0 is used as interrupt source:

Initial=High Inverted=Low

Iniaial_sub()

{ now_int_state=1

_outpd(wBase+0x2a,1) /*(select the inverted signal)*/

ISR_sub()

{

If (now_int_state==0) /* old state=low Æ change to high now */

{

 

 

 

 

now_int_state=1;

/* now int_signal is High

*/

 

/*** application codes are given here ***/

 

 

_outpd(wBase+0x2a,1);

/* select the inverted signal

*/

}

 

 

 

 

else

/* old state=highÆ change to low now

*/

{

 

 

 

 

now_int_state=0;

 

/* now int_signal is Low

/*** application codes are given here ***/

_outpd(wBase+0x2a,0);

}
