While programming the ADC0804 IC what steps are followed?
A. select the analog channel, start conversion, monitor the conversion, display the digital results
B. select the analog channel, activate the ALE signal (L to H pulse), start conversion, monitor the conversion, read the digital results
C. select the analog channel, activate the ALE signal (H to L pulse), start conversion, monitor the conversion, read the digital results
D. select the channel, start conversion, end the conversion

Explanation: While programming the ADC0804 IC firstly we need to select the channel from the A, B, C pins. Then we need to activate the ALE signal, this is needed to latch the address. Then we start the conversion from the WR pin. After monitoring the INTR pin we get to know about the end of the conversion. Then we activate the OE enable to read out data out of the ADC chip.
