Analog-to-Digital Converter (ADC)
15.8.3 ADC Clock Control Register
Technical Data
314
Address:
The ADC clock control register (ADCLK) selects the clock frequency for
the ADC.
ADIV[2:0] — ADC Clock Prescaler Bits
ADICLK — ADC Input Clock Select Bit
Reset:
Read:
Write:
ADIV2, ADIV1, and ADIV0 form a 3-bit field which selects the divide
ratio used by the ADC to generate the internal ADC clock.
Table 15-2
should be set to between 32kHz and 2MHz.
ADICLK selects either bus clock or CGMXCLK as the input clock
source to generate the internal ADC clock. Reset selects CGMXCLK
as the ADC clock source.
