What is TI SPI?
www.ti.com 1.1 Purpose of the Peripheral. The SPI is a high-speed synchronous serial input/output port that allows a serial bit stream of programmed length (2 to 16 bits) to be shifted into and out of the device at a programmed bit-transfer rate.

What is the protocol for the SPI interface?
The SPI interface defines no protocol for data exchange, limiting overhead and allowing for high speed data streaming. Clock polarity (CPOL) and clock phase (CPHA) can be specified as ‘0’ or ‘1’ to form four unique modes to provide flexibility in communication between master and slave as shown in Figure 2.
What are the polarity and clock phases of SPI?
SPI Mode: Polarity and Clock Phase. The SPI interface defines no protocol for data exchange, limiting overhead and allowing for high speed data streaming. Clock polarity (CPOL) and clock phase (CPHA) can be specified as ‘0’ or ‘1’ to form four unique modes to provide flexibility in communication between master and slave as shown in Figure 2.
When to use mode 0 in SPI slave communication?
If CPOL and CPHA are both ‘0’ (defined as Mode 0) data is sampled at the leading rising edge of the clock. Mode 0 is by far the most common mode for SPI bus slave communication. If CPOL is ‘1’ and CPHA is ‘0’ (Mode 2), data is sampled at the leading falling edge of the clock.
What are the four modes of SPI transmission?
By switching the clock polarity (CPOL) and clock phase (CPHA), it can form 4 unique modes to provide flexibility in communication between master and slave. Here is a table listing the four modes of transmission:
