Whenever I enable ICP on the 8535, the chips responds in an odd manner. If I tie the ICP pin (PD6) either high or low the chip goes into an eternal reset mode. If I leave the pin float, it doesn't reset. The only other feature on the chip being used is port C which has an LCD display hooked to it. I am using the STK200. I have tried two chips with no success and I am now officially stuck.
The code I am using worked fine on an 8515. I ported the code to the 8535 with no success. Am I missing a registery setting or something equally foolish? If anyone has an ICP code snippet that works on an 8535 I'd greatly appreciate it since it will eliminate 'coder error'. I can use either assembler or C for CodeVisionAVR. Any other suggestion?
