after looking at the juli.c, raymond has explained to me the meaning of
the values under the /* GPIO Pins */


#define GPIO_ANAIN_MONITOR      (1<<13) 

i wanted to know wat the 13 means, and ray said it was the gpio pin.
where do i find a table of gpio description (eg. AMAIN_MONITOR) and
available definitions on the vt1724.
