Hi,
i'm using BN761 with asm and C. Controllers are AT89C51RC2 and AT89C5131. When i'm simulation a Project, the time runs too fast (as if X2-Mode was active - which isn't).
Quick'n'Dirty Workaround is setting the target-frequency to 6.00MHz instead of 12.00MHz.
With older Versions, this worked correctly.
Any ideas?

regards B. Spitzer

We'll check and fix this issue for the next release (that will come soon).

Found a workaround. When i select the AT89C51 Microcontroller, the timing is correct. Other peripherals of the AT89C51RC2 or AT89C5131 aren't used, so i'm fine with that for the moment.
