EINT0 is connected to the ENC28J60, and is reserved, i.e. not being used now but
that may change.
EINT1 is connected to BOOT and pulled up. The present firmware uses this for
remote debugging, and should stay reserved, though in the next firmware that
will be disabled (a new ARMweb firmware will be posted this weekend)
EINT2 is pulled up through the LED
While EINT2 could be used by ON EINT2, future devices will not support this
(like the LPC175x which has more general interrupt on pin features)
EINT3 is not used
Note that EINT0-3 can be remapped by the PINSEL hardware.

EINT1 is available
EINT2 is used by the firmware for remote debugging.

OK, RIGHT!
EINT1 is available
BUT LOOKS THAT INT1 IS USED FOR CHIP SELECT THE ENC28J60 AND BOOT/P0.14. THEN
INT1 IS BUSY ?
EINT2 is used by the firmware for remote debugging.
MAY I USE IT ?
yes
change? Unlikely.

Re: ARMweb EINT pins
Actually EINT2 is available, EINT1 is used by firmware for remote debugging (my
mistake).
EINT0 is currently not used, and may be available (I don't know if the ENC28J60
asserts it or not, but the firmware ignores that now).

EINT0 and EINT2 are connected on the ARMexpress (as shown in the help file)
BASIC can use INT SUB to engage the interrupt.
In C, details on interrupt code in the User Manual, files posted here on the
Forum, or in the C sources available from Coridium.
