5. The ADC writes a new data result every 256 system clock cycles. For each completed
6. To disable continuous conversion, clear the CONT bit in the ADC Control Register to 0.
The ADC is able to interrupt the CPU when a conversion has been completed. When the
ADC is disabled, no new interrupts are asserted; however, an interrupt pending when the
ADC is disabled is not cleared.

Set CEN to 1 to start the conversions.
CEN resets to 0 to indicate the first conversion is complete. CEN remains 0 for all
subsequent conversions in continuous operation
An interrupt request is sent to the Interrupt Controller to indicate the conversion is
