Hi:
I can't switch ADS8332 mode by writing CFR. When I write CFR and read back, the CFR seems not write into ADS8332, when I read back, it only shows default value. Can Someone help to check timing or what I should notice when write/read command:
Q1: When is right time to configure ADS8332. For example, after power on reset, should I wait CONVST or EOC to be "1'/'0' then I can write it.
Q2: When CFR will update after write new value, should I wait for some time?
Q3: Is there any timing I should modify to make CFR update successful (please help to check below timing).
Fig 1: Global view of write 0xEDFF to ADS8332 then read back CFR by 0xC000. (red line: CSB, yellow: clk, green: SDO, blue: SDI)
Fig2: zoom in for send 0xEDFF to ADS8332.
Fig3: zoom in for reading back CFR.
Fig 4 (below for reference): If I use default mode, I can read AD data (with tag) back, it seems timing is OK. The tag will be 0->1-> ...->7->0..., thus circuit and ADS8332 itself seems fine.
