Signal assignments

USB device data

The two USB data pins attach to the controlled-impedance differential pair.

I²C boot interface

A supported boot EEPROM can supply descriptors or firmware. Use pull-ups even when booting without one.

16-bit slave FIFO data and controls

Firmware selects the slave FIFO mode and controls polarity and endpoint configuration.
