EINT1 can be configured to the two pins you have already found. What
makes you think that the EINT1 function can be routed to another pin
which is not documented? P1.17 has only two functions: GPIO and
"something" for the Trace-Interface - see user's manual pin description
tables. If the frequency is not too high you could poll any GPIO-pin in
a timer-ISR to detect a change.
