1. USB Controller
The Cypress CY7C67300 embedded USB host controller provides high-speed USB
connectivity for the board, and supports host and peripheral modes of operation (see
"2. USB Peripheral Port"
Serial Interface Engines (SIE) that can be used independently. SIE1 is connected to the
USB host port ("3. USB Host
("2. USB Peripheral Port").
The USB controller is equipped with an internal microprocessor to assist in processing
USB commands. The firmware for this processor can be stored in its dedicated I
EEPROM (U41) or downloaded from a host computer through the USB peripheral port
(below). Jumper JP1 can be installed (shorting pins 1 and 2) to prevent the USB
controller from executing firmware stored in the I
for the USB interface are shared with the System ACE interface, as identified in
Table 1-1.
