i.MX25 wake on FEC interrupt (from stop mode) possible?

Hello,

Our target wakes on the FEC interrupt when returning from wait mode.  We would it to wake on FEC interrupt from stop mode.  This doesn't seem to work.  After reviewing the RM, I believe this is because the AHB bus clocks are off. 

The FEC has two clocks enabled by default (AHB and IPG).  I'm having a hard time understanding what the IPG bus is.  My motivation is to configure the IP bus such that we can wake on an FEC interrupt in stop mode.  Is this possible? 

 

Thanks!

Stephen

 

P.S. An image of the iMX25 clock tree will be worth it's weight in gold!
