The user manual for the LPC23xx series (UM10211, 29 oct 2007) says in paragraph 7.3 of the CAN chapter:
"Each Receive and Transmit interrupt request from each controller is assigned its own channel in the Vectored Interrupt Controller (VIC), and can have its own interrupt service routine. The 'other status' interrupts from all of the CAN controllers, and the Acceptance Filter LUTerr condition, are ORed into one VIC channel."
This seems to indicate that I can have five (or possibly three) ISR for CAN. Is this really true?
Chapter 7, table 7-79, only describes the VIC as having a single channel (23) for all CAN interrupts.
What makes it extra interesting is that the uVision dialog for the VIC shows 5 channels named 20 - Brown-out, Can1 Tx, Can1 Rx, Can2 Tx and Can2 Rx. This besides the CAN channel at 23.
