Some signal in the sequence diagram are
"_______/ ________" but some are "_______| |________" Re-read that datasheet again carefully - note that things happen on the edges of the IO Clock and CS lines - so they are shown as "_______| |________"The Address & Data lines just need to be stable at the piont when the IO Clock and/or CS edges occur - so they are shown as "_______/ ________" Stanley Lio said:
So when should I change the state of the address line? It doesn't matter when you change it; what matters is that it is stable when the ADC reads it - on the rising edge of the clock. Stanley Lio said:
I don't know when the ADC will read the address data given by the MPU. Read the Control Sequence again carefully: Addresses are shifted in on the rising clock edges. Data is shifted out on the falling clock edges. Be sure to read the notes under the timing diagram on p3. |
