This is a group for folks designing and programming embedded systems using the Rabbit Semiconductor C-programmable microcontroller. Rabbit Semi is a spin-off from Z-World who makes a variety of embedded modules and tools. This group is not affiliated with either Rabbit or Z-World, but is a user forum for sharing ideas, asking questions, flaunting knowledge, and other typical user group stuff. The Rabbit is a powerful uC, supported by a full-featured C-compiler.
Clearing serial interrupt using Dynamic C inside ISR - thomuh - Oct 21 12:30:52 2009
Hello all,
I am writing an ISR for serial port C. I know that the best way to write ISR's is in assembly language, but how can I clear an interrupt produced by a byte that arrived to serial port C using Dynamic C inside an ISR?
If the ISR is written in assembly, just by doing:
ioi ld a, (SCDR)
will clear the interrupt right? Or do I still need IPSET 3 for example?
Thanks for your help,
