QAD7124-8 Is the serial interface reset when is taken high?
AYes. Each time that is taken high, the serial interface is reset. When is
taken low, the serial interface is in a state where it expects a write to the
communications register, indicating the next operation. This feature is useful
as it allows the user to reset the serial interface.
When reading or writing to the AD7124-8, a user can transmit the data as a
continuous stream or the data can be split into bytes. For example, if writing
24 bits to the ADC, all 24 bits can be transmitted continuously or the data can
be divided into 8-bit words. However, if the data is divided into bytes, must
be held low until all bytes are transmitted.
