MPC5777C MCAL4.3 cannot get into any other interrupt because of Global interrupt closed unexpectedly

[Zhongling_Lang]

Hi All,

I'm developing demo code with MPC5777C MCAL4.3, I implement a SDADC demo code by myself and enable the SDADC FIFO interrupt, but the FIFO interrupt will close global interrupt(MSR[EE=0]) and code cannot get into any other interrupts. if i enable the global interrupt in the end of FIFO interrupt and the code will get into IVOR13/14.

So how to deal with the interrupt handler implemented by user and how to resolve this issue.

By the way, also some customers have this issue in MCAL4.0 and user's interrupt handler will close global interrupt unexpectedly.

I have resolve this issue, because some inappropriate configuration with sdadc and just call the EXIT_INTERRUPT in the end of interrupt handler.
