CAN interrupt wake up in lpc2468

Hi, I am trying to get my board into power down mode and then wake on CAN activity, but am having problems.

I can mange to get into power down mode.

If I use a EINT0 pin to exit power down mode I have no problems at all, it works every time.

Has anyone here used power down or sleep modes with CAN ?

The only bit set in the INTWAKE register is the CAN bit.

Are there any other bits I need to set ? I can only assume I have missed something somewhere.

thanks
RUPA
