Hello,
I work with an controller (with two crystals - 32.768kHz and 18.432MHz). When the controller starts only the 32.768kHz crystal is working - the main crystal is only working if I turn it on by software.
At the moment I've no main crystal - only the 32.768kHz crystal installed; if I download some code to the internal memory I use for the "max. JTAG clock option" 1MHz - what is the relation between this Jtag clock and the crystal from the controller? I've thought, that I'll not be able to store some code within the controller with a higher frequency then the crystal is running...
best regards Scott Alan
