An ADM3202 RS232 driver is implemented for signal adaptation between RS232 signals (RXD, TXD) on
the debug port connector and AT91CAP9 Debug unit 3.3V signals (DRXD, DTXD).
The implementation is shown below:
The two USB v2.0 Host interfaces are managed by the AT91CAP9 USB Host port, which handles OHCI
protocol as well as USB v2.0 Full-speed and Low-speed protocols.
Two NUF2101 USB filters are implemented for ESD protection and line adaptation (26.3Ω to 33.7Ω).
One 0603 footprint is implemented on each signal to adjust 39Ω line impedance if necessary.
One 500 mA SMD fuse is added on 5V power supply of each port.
