Please refer to chapters 8.4.4 and 9.4.5 of the Universal Serial Bus Specification, Rev. 1.1 to get more information on the
STALL handshake.
ISOERROR: a CRC error has been detected in an isochronous transfer
Read
0 = No error in the previous isochronous transfer.
1 = CRC error has been detected, data available in the FIFO are corrupted.
Write
0 = reset the ISOERROR flag, clear the interrupt.
1 = No effect.
• TXPKTRDY: Transmit Packet Ready
This flag is cleared by the USB device.
This flag is set by the USB device firmware.
Read
0 = Data values can be written in the FIFO.
1 = Data values can not be written in the FIFO.
Write
0 = No effect.
1 = A new data payload is has been written in the FIFO by the firmware and is ready to be sent.
This flag is used to generate a Data IN transaction (device to host). Device firmware checks that it can write a data payload
in the FIFO, checking that TXPKTRDY is cleared. Transfer to the FIFO is done by writing in the UDP_FDRx register. Once
the data payload has been transferred to the FIFO, the firmware notifies the USB device setting TXPKTRDY to one. USB
bus transactions can start. TXCOMP is set once the data payload has been received by the host.
• FORCESTALL: Force Stall (used by Control, Bulk and Isochronous endpoints)
Write-only
0 = No effect.
1 = Send STALL to the host.
Please refer to chapters 8.4.4 and 9.4.5 of the Universal Serial Bus Specification, Rev. 1.1 to get more information on the
STALL handshake.
Control endpoints: during the data stage and status stage, this indicates that the microcontroller can not complete the
request.
Bulk and interrupt endpoints: notify the host that the endpoint is halted.
The host acknowledges the STALL, device firmware is notified by the STALLSENT flag.
• RX_DATA_BK1: Receive Data Bank 1 (only used by endpoints with ping-pong attributes)
This flag generates an interrupt while it is set to one.
Write (Cleared by the firmware)
