    USB operations: 8MHz and 16MHz. The STK526 comes with a default 8MHz crystal oscillator. If STK526 is connected to an STK500 and the jumpers “STKX1” and “STKX2” are set, the STK526 microcontroller operates with the “STK500 Osc” frequency parameter. The STK500 clock prevails over the STK526 crystal.
