ADICLK — ADC Input Clock Select Bit
Freescale Semiconductor
ADICLK selects either the bus clock or CGMXCLK as the input clock source to generate the internal
ADC clock. Reset selects CGMXCLK as the ADC clock source.
If the external clock (CGMXCLK) is equal to or greater than 1 MHz, CGMXCLK can be used as the
clock source for the ADC. If CGMXCLK is less than 1 MHz, use the PLL-generated bus clock as the
clock source. As long as the internal ADC clock is at approximately 1 MHz, correct operation can be
guaranteed.
1 = Internal bus clock
0 = External clock (CGMXCLK)
