My ATMEGA88V clock is running at 1/8th the correct speed. This is even though I programmed off the 1/8 flag, and also turned off the clock divider at startup (CLKPR = 0;); I am using a full swing external crystal at 3.6864 MHz.
I verified that the clock is too slow by setting the flag to make it output on B0, and looking at it with a scope.
The 88V is a slow version (<10MHz). Is it possible that it has a weirdness in this area?
Note that it also has a signature different from the one in the manual.
Any help would be appreciated.
