Hi~ :)
I use ADS7863 with McBSP of a C2812.
The operation mode that I use is PSEUDO-DIFFERENTIAL MODE II.
I have a problem that communication error occurs by external noise during ADS7863 communication.
In case of normal operating state, the SDOA was shown as following order. "Channel A(CHA0+/CHA0-) -> Channel B(CHB0+/CHB0-) -> Channel A(CHA1-/CHA0-) -> Channel B(CHB1-/CHB0-) -> … "
In case of abnormal operating state that communication error occurs, the SDOA was shown as following order despite CONVST, RD, and SDI were entered normally.
"Channel B -> Channel A -> Channel B -> Channel A -> …. " or "Channel A -> Channel A -> Channel B -> Channel A -> OR Channel A -> Channel A -> Channel B -> Channel A -> …"
Q1. Is it possible to solve this communication problem with software reset of ADS7863?
Q2. What is the difference between software reset and hardware reset?
Q3. If it is possible to solve the problem with software reset, could you inform us that the detail procedure of software reset.
Q4. As an additional question, there are additional features in table 5 and 6 in manual. Is it right to set the following parameters for device reset.
P0:P0=[0:1], A2:A1:A0=[1:0:1]
