Hello Uwe,

Contrary to what I said previously I have to keep possible_status
variable as for one irq enabled we allow several events.
For example, ITBUFEN allows to generate an irq for RXNE and for TXE events.
So, using status = read_from_status_register() &
read_from_interrupt_enable_register(); is not possible.
Best regards,
Cedric
