8.3.12
Function Endpoint 1,2,3 Service Routine Register – FCSR1,2,3
Bit 7..4 – Reserved
These bits are reserved in the AT43USB325 and will read as zero.
Bit 3 – STALL SENT
The USB hardware sets this bit after a STALL has been sent to the host. The firmware uses this
bit when responding to a Get Status[Endpoint] request. It is a read only bit and that is cleared
indirectly by writing a one to the STALL_SENT_ACK bit of the Control and Acknowledge
Register.
Bit 2 – Reserved
This bit is reserved in the AT43USB325 and will read as zero.
Bit 1 – RX OUT PACKET
The USB hardware sets this bit after it has stored the data of an OUT transaction in the FIFO.
While this bit is set, the hardware will NAK all OUT tokens. The USB hardware will not overwrite
the data in the FIFO except for an early set-up. RX OUT Packet is used by a BULK OUT or ISO
OUT or INT OUT endpoint.
Setting this bit causes an interrupt to the microcontroller if the interrupt is enabled. FW clears
this bit after the FIFO contents have been read by writing a one to the RX_SETUP_ACK bit of
the Control and Acknowledge Register.
Bit 0 – TX COMPLETE: Transmit Completed
This bit is used by the endpoint hardware to signal to the microcontroller that the IN transaction
was completed successfully. This bit is read only and is cleared indirectly by writing a one to the
TX_COMPLETE_ACK bit of the Control and Acknowledge Register.
