Hi All,
I am getting a bit confused about the high-resolution extension of the xmega. On one hand, the manual seems to imply that the counter can be clocked at 128 MHz, if one uses the 32-MHz system clock. On the other hand, the manual also says that the two least significant bits of the counter are discarded. So, why would one want to use the higher clock speed, if the result of that is thrown away? Can, then, the xmega be used for measuring times at the 10-ns level? If yes, how should one set up the counter for that?
Thanks,
Zoltán
