+description: |
+  USI IP-core provides selectable serial protocol (UART, SPI or High-Speed I2C).
+  USI shares almost all internal circuits within each protocol, so only one
+  protocol can be chosen at a time. USI is modeled as a node with zero or more
+  child nodes, each representing a serial sub-node device. The mode setting
+  selects which particular function will be used.
