Address:
Address:
One 8-bit result register, ADC data register (ADR), is provided. This
register is updated each time an ADC conversion completes.
The ADC clock register (ADCLK) selects the clock frequency for the
ADC.

ADIV[2:0] form a 3-bit field which selects the divide ratio used by the
ADC to generate the internal ADC clock.
available clock configurations. The ADC clock should be set to
approximately 1 MHz.
