operation timing diagrams
The nonconversion operation includes FIFO READ and WRITE CFR. Both do not perform a conversion. The
conversion operation performs one of four types of conversion: mode 00, 01, 10 and 11
write cycle (WRITE CFR Command): Write cycle does not generate EOC or INT, nor does it carry out any
conversion.
