Assume P1.3 is properly configured for analog input. If the voltage at P1.3 is 1.0V
and if ADC1 is initialized according to the code below, what is the A/D conversion
result, "ADResult"?
void ADC_Init(void)
{
REF0CN = 0x03;
ADC1CN = 0x80;
ADC1CF = 0x01;
}
Student Response
Correct
Answer
A. ADResult < 100
B. 100 <= ADResult < 120
C. 120 <= ADResult < 140
D. 140 <= ADResult < 160
E. 160 <= ADResult < 180
F. 180 <= ADResult < 200
G. 200 <= ADResult
H. indeterminate
