Read/Write 8-bit data of 8254

(Read/Write): wBase+0xe0/ 0xe4/ 0xe8

Bit 2

Bit 1

Bit 0

(Read/Write): wBase+0xec= 8254 control word
(Read/Write): wBase+0xe0= 8254-counter-0
(Read/Write): wBase+0xe4= 8254-counter-1
(Read/Write): wBase+0xe8= 8254-counter-2

For example:
outportb(wBase+0xec,0x30);

/* Counter0, mode-0 */

outportb(wBase+0xe0,0xff);

/* write to low byte first */

outportb(wBase+0xe0,0xff)

/* write to high byte second */

/* Then Counter0 will down count from 0xffff */



The configuration of 8254 counter:
