1.21.1 USB Function Control Unit (USBFCU)
The implementation of the USB by this device is ac-
complished chiefly through the device’s USB Function
Control Unit. The Function Control Unit’s overall pur-
pose is to handle the USB packet protocol layer. The
Function Control Unit notifies the MCU that a valid to-
ken 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 regis-
ter (see Figure 1.51).
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
1.21.1.1 Serial Interface Engine
The SIE interfaces to the USB serial data and handles
deserialization/serialization of data, NRZI encoding/
decoding, clock extraction, CRC generation and
checking, bit stuffing, and other specifications pertain-
ing to the USB protocol such as handling inter-packet
time-outs and PID decoding 1.
1.21.1.2 Generic Function Interface
The GFI handles all USB standard requests from the
host through the control endpoint (endpoint 0), and
handles Bulk, Isochronous and Interrupt transfers
through Endpoints 1-4. The GFI handles read pointer
reversal for re-transmission of the current data set;
write pointer reversal for re-reception of the last data
set, and data toggle synchronization.
1.21.1.3 Serial Engine Interface Unit
The SIU block decodes the Address and Endpoint
fields from the USB host.
1.21.1.4 Microcontroller Interface Unit
The MCI block handles the microcontroller interface
and performs address decoding and synchronization
of control signals.
1.21.1.5 USB Transceiver
The USB transceiver, designed to interface with the
physical layer of the USB, is compliant with the USB
Specification (version 1.1) for high speed devices. It
consists of two 6-ohm drivers, a receiver, and Schmitt
triggers for single-ended receive signals.
