An embedded system has a 12-bit analog-to-digital converter(ADC),with a multiplexed input, as one of its peripherals
-There are four mgains to select an input voltage range.
-There are eight channels which can be selected to drive the ADC
-.The sample clock can be programmed to be one of eight frequencies based on the system clock.

Which of the following statements are correct regarding accessing and controling the ADC?

To reduce the number of pins on the microcontraler the ADC may send its data using a serial protocol such as SPl or I2C
A minimum of 12 bits are needed to control the gain,channel selection,and sample frequency of the ADC
A 20-bit port will be sufficient to control the ADC and access its result
A copy of the ADC control bits can all be stored in a single byte in memory
A faster ADC clock will reduce the likelihood of missing samples if the program cannot keep up with the ADC data
