1.2.18.1 USB Function Control Unit (USB FCU)
The implementation of the USB by this device is accomplished chiefly through the device’s USB Func-
tion Control Unit (See Figure 1.29). The Function Control Unit’s overall purpose is to handle the USB
packet protocol layer. The Function Control Unit notifies the MCU that a valid token has been received.
When this occurs, the data portion of the token is routed to the appropriate FIFO. The MCU transfers
the data to, or from, the host by interacting with that endpoint’s FIFO and CSR register.
The USB Function Control Unit is composed of five sections:
Serial Interface Engine (SIE)
Generic Function Interface (GFI)
Serial Engine Interface Unit (SIU)
Microcontroller Interface (MCI)
USB Transceiver
1.2.18.1.1 Serial Interface Engine
The SIE interfaces to the USB serial data and handles deserialization/serialization of data, NRZI encoding de-
coding, clock extraction, CRC generation and checking, bit stuffing, and other items pertaining to the USB pro-
tocol such as handling inter-packet time-outs and packet ID (PID) decoding.
