2 HOST Interface
W5500 provides SPI (Serial Peripheral Interface) Bus Interface with 4 signals (SCSn,
SCLK, MOSI, MISO) for external HOST interface, and operates as a SPI Slave.
The W5500 SPI can be connected to MCU as shown in Figure 4 and Figure 5
according to its operation mode (Variable Length Data / Fixed Length Data Mode)
which will be explained in Chapter 2.3 and Chapter 2.4.
In Figure 4, SPI Bus can be shared with other SPI Devices. Since the SPI Bus is
dedicated to W5500, SPI Bus cannot be shared with other SPI Devices. It is shown in
Figure 5.
At the Variable Length Data mode (as shown in Figure 4), it is possible to share the
SPI Bus with other SPI devices. However, at the Fixed Length Data mode (as shown in
Figure 5), the SPI Bus is dedicated to W5500 and cant be shared with other devices.

Figure 5. Fixed Length Data Mode (SCSn is always connected by Ground)
The SPI protocol defines four modes for its operation (Mode 0, 1, 2, 3).Each mode
differs according to the SCLK polarity and phase. The only difference between SPI
Mode 0 and SPI Mode 3 is the polarity of the SCLK signal at the inactive state.
With SPI Mode 0 and 3, data is always latched in on the rising edge of SCLK and
always output on the falling edge of SCLK.
