When i use mcf52223 adc to do my work, i noticed that the "MCF52223 ColdFire® Integrated Microcontroller Reference Manual" page 25-33 tells the ADC clock is gated by ADC bit of SIM_PCE register of SIM module. But I can not find the description on SIM_PCE register. Is it an error or useless register. Does it affect the ADC operation?
Thanks millions on any hints
