Note. Refer to Sec. 3.1 for more information about wBase.

EN0=0Æ disable PC0 as a interrupt signal (default)

EN0=1Æ enable PC0 as a interrupt signal

outportb(wBase+5,0);	/* disable interrupt	*/
outportb(wBase+5,1);	/* enable interrupt PC0	*/
outportb(wBase+5,0x0f);	/* enable interrupt PC0, PC1,PC2,PC3	*/
