Enum SpiMode
Defines how data is synchronized between devices on a SPI bus. Clock Polarity (CPOL) determines if clock signal is low or high when in idle state. Clock Phase (CPHA) determines when data is sampled relative to the clock signal.

Syntax
public enum SpiMode
Fields
Name | Description |
---|---|
Mode0 | CPOL 0, CPHA 0. Polarity is idled low and data is sampled on rising edge of the clock signal. |
Mode1 | CPOL 0, CPHA 1. Polarity is idled low and data is sampled on falling edge of the clock signal. |
Mode2 | CPOL 1, CPHA 0. Polarity is idled high and data is sampled on falling edge of the clock signal. |
Mode3 | CPOL 1, CPHA 1. Polarity is idled high and data is sampled on rising edge of the clock signal. |
