Specifications of AT91RM3400-DK

• Contents: Evaluation Board, Software and Documentation
• Processor To Be Evaluated: AT91RM3400
• Data Bus Width: 32 bit
• Interface Type: RS-232, USB
• For Use With/related Products: AT91RM3400
• Lead Free Status / RoHS Status: Contains lead / RoHS non-compliant

• EP7INT: Endpoint 7 Interrupt Status
0 = No Endpoint7 Interrupt pending.
1 = Endpoint7 Interrupt has been raised.
Several signals can generate this interrupt. The reason can be found by reading USB_CSR7:
EP7INT is a sticky bit. Interrupt remains valid until EP7INT is cleared by writing in the corresponding USB_CSR7 bit.
• RXSUSP: USB Suspend Interrupt Status
0 = No USB Suspend Interrupt pending.
1 = USB Suspend Interrupt has been raised.
The USB device sets this bit when it detects no activity for 3ms. The USB device enters Suspend mode.
• RXRSM: USB Resume Interrupt Status
0 = No USB Resume Interrupt pending.
1 =USB Resume Interrupt has been raised.
The USB device sets this bit when a USB resume signal is detected at its port.
• EXTRSM: External Resume Interrupt Status
0 = No External Resume Interrupt pending.
1 = External Resume Interrupt has been raised.
This interrupt is raised when, in suspend mode, an asynchronous rising edge on the send_resume is detected.
If RMWUPE = 1, a resume state is sent in the USB bus.
• SOFINT: Start of Frame Interrupt Status
0 = No Start of Frame Interrupt pending.
1 = Start of Frame Interrupt has been raised.
This interrupt is raised each time a SOF token has been detected. It can be used as a synchronization signal by using
isochronous endpoints.
• ENDBUSRES: End of BUS Reset Interrupt Status
0 = No End of Bus Reset Interrupt pending.
1 = End of Bus Reset Interrupt has been raised.
This interrupt is raised at the end of a USB reset sequence. The USB device must prepare to receive requests on the end-
point 0. The host starts the enumeration, then performs the configuration.
• WAKEUP: USB Resume Interrupt Status
0 = No Wakeup Interrupt pending.
1 = A Wakeup Interrupt (USB Host Sent a RESUME or RESET) occurred since the last clear.
