interface ADC0804

Hello Folks,

I am trying to interface the ADC0804, 8-bit output to 8 input pins of a CPLD. I intend to provide 1MHz clock frequency to the ADC and use a system clock for the CPLD at a lower frequency say 500 kHz. The reasoning bieng the ADC will have plenty of time to change its value within a system clock cycle. I have looked at the control steps for the ADC and have attempted to initiate a start conversion cycle. Could someone please let me know if I am going about this correctly. Thank you in advance. The code is not complete as it does not read the value yet. I have to convert the crystal frequency of 25MHz into a squarewave in code.

Jag.
