Void adc_init(void)
{
ADMUX = (1< ADSRA = (1< }
int readAdc (char chan)
{
ADMUX = (1< ADSRA = (1< while (ADSRA & (1< return ADCW;
}

In the above code, macros and bits definitions are used (i. e ADMUX, REFSO) instead of pointers, etc. Add a comment for each line of code that describes what each line does. Describe the function of ADCW.

This code tells us that When ADCL is read the ADC register is not updated consequently,if the result is  left adjusted and no more than 8 bit precision is required it is sufficient to read ADCH.

solution:

the auto-correct option of the auto-correct tool enables you to add and delete words that do not follow abbreviation rules because:

it is a feature that allows outlook to correct common spelling and typing errors and to replace characters with symbols. we can also can use auto-correct as a shortcut, which means we can type a small string of characters and have those characters replaced by a longer string.
