You should look at the DIO Port header, there are 8 GPIO :
DIO_08, DIO_09, ..., DIO_16
DIO_15 DIO_08
DIO_14 DIO_09
15 13 11 9 7 5 3 1
+--+--+--+--+--+--+--+
| |
+--+--+--+--+--+--+--+
16 14 12 10 8 6 4 2
3.3V | GND
DIO_16
Proc pin:
EGPIO_8 = DIO_08
EGPIO_9 = DIO_09
...
EGPIO_15 = DIO_15
FGPIO_0 = DIO_16
According to cirrus datasheet (TS-7200):
Port EGPIO is 4ma / Pull-up
Port FGPIO is 8ma / Pull-up
You should also have a look at Technologic Systems documentation, pin
can source 4ma or sink 8ma.
For software issues, I advice you to use a small program written by Jim
Jackson called "adio", it will help you to manipulate io from command line.
