Hello. I'm using Silabs C8051F120 microcontroller and I have a problem during simulation in Keil C51 8.05. The problem is the following: after building I start simulator and make Run. Program is being run approx 1 minute and after that uVision crashed (Windows XP gets message that there was exception produced by division by zero). This is usually occured when I'm not using breakpoints in simulator. Anybody faced with the same problem?
