Normaly, my generic clock generators of my SAMD10 D14work very fine with my own drivers (no ASF) for TC1, TC2,
ADC, SERCOM. But when I program TCC0, it does not show any life. I suspected no clock at its prescaler, and I
seem to be right. Clock generator 0 with XOSC works well, as all the drivers cooperate with it. When I enable
CLKTRL.CLKEN=1, and I read back this register, this bit is set to 0. If I use any other
CLKTRL.ID, which is not 0x11, CLKTRL.CLKEN=1 is correctly shown. Why???
Even if I enable CLKEN at the beginning, high level is reset, due to the ID=0x11, why?
