I have been trying to get QSPI interrupts to work for quite a while,=20
following the user manual and the mpc555 interrupts application note,=20
with no luck. I have put a breakpoint at location 500, where it should=20
get before vectoring to the ISR, but it never gets there.
Has anyone else been through this, or have any examples of how to do it?
I am transferring data to the device, but I never get an interrupt when=20
the queue is empty, even though I have followed the 5 steps outlined in=20
the application note, but no luck.
Larry
