Using the SX48 produced by UBICOM (SCENIX), we find an occasional unpleasant habit of not properly handling the interrupt routine at all times.

The condition arises when The RTCC hits zero when a call to the beginning of a page is processed.

The result of this action is that, on leave of the ISR, the interrupt flag will not be reset. A new interrupt is not possible.

If the program flow of the SX48 depends on external input e.g. Keyboard, RS232.. the outcome is unpredictable.

QUESTION FOR THE SX48 USERS

We would like to know if there are SX48 users who have the same or similar problems with interrupts. We are interested in the ease we can reproduce the error, the impact on systems and if any valid workaround was found.

The level of support by Ubicom (Scenix) and if your project was stopped or redesigned with another processor.

As I have answered MANY times, you are NOT blocked. That ip is not in my blocking list. If it were, you would see a specific message and have a form to unblock. What is happening is some sort of bug in your ISP, or a routing failure in the internet or some sort of bug in my web server.' at: '' sxcorreo@ciudad.com.ar asks:
    Hi James.
    Is there any way to be unblocked to this site ???????
    If you won't simply answer, NO, and I'll be allways using this Proxy server, just see this 24.232.248.19, OK ?? from this IP everybody could RIP or download or use the some software to download all the site ( like teleport ), and tomorrow change the IP again, if you block it !!!, is that way, that you want ?.
    Unblock me please, or let me know if you want that OK.
