Hello!
I am porting ecos to FR30 / FR50 archtitecture from Fujitsu.
I have a question to the interrupt controller management macros.
The FR30 architecture has 48 different interrupt sources. Every interrupt a
level can be assigned. 15 different levels are possible.
What can I do to have that fit best into ecos, which seems to expect to be
able to mask every single interrupt by its vector number ?
By the way, the interrupt levels of the fr30 define some sort of priority
management. A higher priotized interrupt can interrupt a lower priorized one.
Have you looked at how it was done on the other Fujitsu platforms (hal/frv)?
