This book is for developers who design and program devices that use the
Universal Serial Bus (USB) interface. The goal is to introduce you to USB
and to help you get your devices up and communicating as quickly and easily
as possible.
Full compliance with the USB Specification v1.1 and USB CDC v1.1
Support the RS232 Serial interface
Support automatic handshake mode
Support Remote wake-up and power management
256 bytes buffer each for upstream and downstream data flow
Support default ROM or external EEPROM for device configuration
On chip USB transceiver
On chip crystal oscillator running at 12M Hz
Supports Windows 98/SE, ME, 2000, XP, Windows CE3.0, CE .NET, Linux, and Mac OS
28 Pins SOIC package

This document describes how to switch to and program the unisersal serial bus (USB)
analog phase-locked loop (APLL) on the C5506/C5507/C5509A devices. Example
assembly programs for programming and switching to and from the APLL are also
provided in the attached zip file. It is assumed that the reader is familiar with the use
and operation of the C5506/C5507/C5509A USB digital phase-locked loop (DPLL) and
C55x™ Digital Signal Processor (DSP) IDLE procedures.
with serial bus (Universal Serial Bus) is used to apply USB peripherals connected to the mainframe external bus structure, it is mainly used in medium-speed and low-speed peripherals
Very simple USB 1.1 PHY. Includes all the goodies: serial/parallel
conversion, bit stuffing/unstuffing, NRZI encoding decoding. Uses a
simplified UTMI interface. Currently doesn t do any error checking in
the RX section [should probably check for bit unstuffing errors].
Otherwise complete and fully functional.
There is currently no test bench available. This core is very simple
and is proven in hardware. I see no point of writing a test bench at
this time.
