USB Device Port

• Two-pin UART

– Implemented features are 100% compatible with the standard Atmel USART

– Independent receiver and transmitter with a common programmable Baud Rate

Generator

– Even, Odd, Mark or Space Parity Generation

– Parity, Framing and Overrun Error Detection

– Automatic Echo, Local Loopback and Remote Loopback Channel Modes

– Interrupt generation

– Support for two PDC channels with connection to receiver and transmitter

• Debug Communication Channel Support

– Offers visibility of COMMRX and COMMTX signals from the ARM Processor

– Interrupt generation

• Chip ID Registers

– Identification of the device revision, sizes of the embedded memories, set of

peripherals

• Up to 32 programmable I/O Lines

• Fully programmable through Set/Clear Registers

• Multiplexing of two peripheral functions per I/O Line

• For each I/O Line (whether assigned to a peripheral or used as general purpose I/O)

– Input change interrupt

– Glitch filter

– Multi-drive option enables driving in open drain

– Programmable pull up on each I/O line

– Pin data status register, supplies visibility of the level on the pin at any time

• Synchronous output, provides Set and Clear of several I/O lines in a single write

• Compliance with Open HCI Rev 1.0 specification

• Compliance with USB V2.0 Full-speed and Low-speed Specification

• Supports both Low-speed 1.5 Mbps and Full-speed 12 Mbps USB devices

• Root hub integrated with two downstream USB ports

• Two embedded USB transceivers

• Supports power management

• Operates as a master on the Memory Controller

• USB V2.0 full-speed compliant, 12 Mbits per second

• Embedded USB V2.0 full-speed transceiver

• Embedded dual-port RAM for endpoints

• Suspend/Resume logic

• Ping-pong mode (two memory banks) for isochronous and bulk endpoints

• Six general-purpose endpoints

– Endpoint 0, Endpoint 3: 8 bytes, no ping-pong mode

– Endpoint 1, Endpoint 2: 64 bytes, ping-pong mode

– Endpoint 4, Endpoint 5: 256 bytes, ping-pong mode
