The serial interface without the slave select pin must use delimiters for the start and stop conditions. Between these delimiters, the address, data, and command words can be transferred. All words must be 8 bits long with MSB transmitted first (see Figure 6-16).
In this mode, a rising edge on data in (I/O_7, pin 24) while SCLK is high resets the serial interface and prepares it to receive data. Data in can change only when SCLK is low, and it is read by the reader on the SCLK rising edge. Communication is terminated by the stop condition when the data in falling edge occurs during a high SCLK period.
