Hi,

maybe you have an old Datasheet. I use one from May 03,2004 it tells 
me:   

VIC-Channel 20 CAN1 Tx
VIC-Channel 21 CAN2 Tx
VIC-Channel 22 CAN3 Tx (LPC2194/2292/2294 only, otherwise Reserved)
VIC-Channel 23 CAN4 Tx (LPC2194/2292/2294 only, otherwise Reserved)
VIC-Channel 24-25 Reserved
VIC-Channel 26 CAN1 Rx
VIC-Channel 27 CAN2 Rx
VIC-Channel 28 CAN3 Rx (LPC2194/2292/2294 only, otherwise Reserved)
VIC-Channel 29 CAN4 Rx (LPC2194/2292/2294 only, otherwise Reserved)
VIC-Channel30-31 Reserved

....and it seems to work.

Regards,

Peter
