#111481 - mess Responding to: ???'s previous message |
It's a mess but I'd guess the worst scenario is true, i.e. 24MHz is the limit for core. There is/was a part called AT89C2051X2, where the datasheet says explicitly so (so the only reason why would one use a 12MHz crystal and the x2 feature on is a hypothetical EM emission reduction).
As far as you have no confirmation from Atmel, you have to assume so, anyway. Jan Waclawek |
