TDC7200: CSB of TDC7200

Hi:

   If  only one TDC7200 is used for the product, can we just connect the CSB pin to the circuit GND all the time?

thanks

    Zhang,

    Yes, if using only one TDC7200 you can assert the CSB pin to GND all the time.

    However CSB is an active-low signal and needs to be low throughout a transaction.De-asserting CSB always terminates an ongoing transaction, even if it is not yet complete. Re-asserting CSB will always bring the device into a state ready for the next transaction, regardless of the termination status of a previous transaction.
