Post by thread:Interruots

Hi there. Hello.. Can you disable interrupts when another interruput is being serviced? Meaning, on my system, port B interrupt needs to be disabled when the receive interrupt is being serviced. Port B interrupt should, however always be set up. Thanks .. -Prashanth

Hi - As far as I remember the GIE (Global Interupt Enable) is cleared when you get an interupt. RETI then sets it back. So to answer your Q: it's done automatecly. /holger {Quote hidden}> ---------- > From: Prashanth Ram[SMTP:spam_OUTpramTakeThisOuTECE.WPI.EDU] > Sent: Thursday, March 18, 1999 4:55 PM > To: .....PICLISTKILLspam@spam@MITVMA.MIT.EDU > Subject: Interruots > > Hi there. > Hello..

>get an interupt. RETI then retfie is the correct opcode.

It definately is what is used by the SX-Key software for the Scenix chips.

Sean, "RETI" is Parallax syntax which is also used in their SX software. For anyone familiar with Parallax/CVASM/805x syntax, the transition to SX is trivial. - Tom At 02:00 PM 3/18/99 -0500, Sean Breheny wrote: {Quote hidden}>At 11:29 AM 3/18/99 -0500, you wrote: >>>get an interupt.
