Hi, It seems there is a problem in clearing interrupts in function cyg_hal_interrupt_acknowledge of the MPC8xxx HAL that would result in simultaneous interrupts being missed.
If there were multiple interrupts being reported, all of them would get cleared when only one is being acknowledged because we read the value, OR it with the mask for acknowledged vector and then write this value. The documentation says we should write 1's to locations that need to be cleared. So I believe there is no need for the read or 'OR' operation. Just write the mask for the vector. I our board we were missing one of the interrupts with the original code. With the modification it is working correctly.
