The following quote is from doc0856.pdf "AVR Instruction Set" (and is valid for all AVRs, including the XMEGAs, btw.): SEI Set Global Interrupt Flag Description: Sets the Global Interrupt Flag (I) in SREG (Status Register). The instruction following SEI will be executed before any pend- ing interrupts. Do you find that a sufficient documentation of this feature?
