Ted:
In debuging the UARTs, I noticed a couple of things about the interrupt
behavior.
1. After executing the reti instruction, simulavr does not execute 2
instructions (the AVR does).
2. I discovered this as part of trying to figure out why I get 2 UDRE
interrupts back to back. I guess I need to find some way to keep the
interrupt callback from issuing a 2nd interrupt until the first gets
processed? Does this sound right? Any suggestions? Thanks.
