Oops, I can't believe I said that! I think it makes more sense that interrupts from *lower* priority sources are masked until HAL_INTERRUPT_ACKNOWLEDGE is called. But really, it is target-specific whether higher, lower, or any are released when HAL_INTERRUPT_ACKNOWLEDGE is called. Not that it makes any difference in HALs that don't support nested interrupts but the macro might have to tickle the interrupt controller and make it happy. -- +--------------------------------------------- | Daniel Helgason <[EMAIL PROTECTED]> -- Before posting, please read the FAQ: http://ecos.sourceware.org/fom/ecos and search the list archive: http://ecos.sourceware.org/ml/ecos-discuss
