ously. The serial clock synchronizes the timing at which information on the two serial data lines are shifted or sampled.
Slave device can be selected individually using the slave select pin (SS pin). For unselected slave devices, data on the
SEI bus cannot be taken in.
During a SEI transfer, data transmission (serial shift-out) and reception (serial shift-in) are performed simultane-
When operating as the master devices, the SS pin can be used to indicate multiple-master bus connection.

The SEI clock allows its phase and polarity to be selected in software from four combinations available by
The clock polarity is set by CPOL to select between active-high or active-low (The transfer format is unaf-
The clock phase is set by CPHA. The master device and the slave devices to communicate with must have the
