Hello, I am running an application where an external reset from a WDT generates a reset on an ST10F168. When the reset occurs, all of PORT6 on the device is momenterally pulled low, then is pulled high again. There is no obviouse reason for this, and it is causing a major problem. The particular problem is with P6.5, which has an external pull up. Any help would be appreciated. Thanks Joe
It looks like some of the lines on P6 are used for bus arbitration (HOLD, HLDA, ...). Since HOLD is P6.5, maybe this is causing the problem. Jon
Cheers Jon. Thats what I thought... Just been through the programmers code, turns out the port pin was being set to output then high after reset, rather than the other way around. The default data value after reset is 0x00, . Problem solved.
