NOTES

1. DATA ACCESS CAN ONLY OCCUR AFTER CONVERSION. BOTH CONVERSION RESULT AND THE CFG REGISTER ARE UPDATED AT THE END OF THE CONVERSION (EOC).

2. A TOTAL OF 16 SCK FALLING EDGES ARE REQUIRED FOR CONVERSION RESULT. AN ADDITIONAL 16 EDGES AFTER THE LAST CONVERSION RESULT ON BUSY READS BACK THE CFG ASSOCIATED

WITH CONVERSION.

3. CS CAN BE HELD LOW OR CONNECTED TO CNV. CS IS SHOWN WITH FULL INDEPENDENT CONTROL.

4. FOR OPTIMAL PERFORMANCE, DATA ACCESS SHOULD NOT OCCUR DURING THE SAMPLING INSTANT. A MINIMUM TIME OF AT LEAST THE APERATURE DELAY,
