Hi guys,

I've been trying to search the forum for an answer, but im not finding one.

[b]Scenario:[/b]
The SX28 is executing code in the ISR.
WKPND_B was cleared on entry to do usual check to see what caused the interrupt.
Now while in the ISR an external source triggers an interrupt, setting the WKPND_B register (I know the WKPND_B register gets set)
The SX now does a RETI

[b]My Question:[/b]
Will this external interrupt and setting of WKPND_B register during the ISR cause the SX28 to jump back into the ISR again??

I really need to be able to catch every single external event, even when they occur during the ISR!

Thanks in advance for any help/info
Cheers,
Andy
