value$2=$ ADC$12$MEM$8$ & $0$x$0$FFF;

value$3=$ ADC$12$MEM$9$ & $0$x$0$FFF;

b$.$ What is the code value in value$3$ for the default voltage on that input channel? What is

the voltage value on the corresponding analog input if value$1=0$x$0410?$ What is the code

value in value$2$ if the voltage on the corresponding input is $1\mathrm{.}56$V$?$
