Figure 3.1. Recommended Schematics: Connecting WGM110 with an External Host Using the UART Interface (USART0 Loc 0)
Note: In the figure above the UART interface is wired using USART0 Location 0 pins.
Note: If handshaking is required, then connect external host CTS to PE13 and external host RTS to PE12.
Note: A programming connector, as shown in the schematics, must be available in the design to enable WGM110 firmware update.
3.1.2 SPI
SPI is one of the available host interfaces on the WGM110 Module. SPI must be always enabled and configured by the user, because it
is not enabled or configured as default.
The table below shows the features of the SPI host interface:
