AT43USB353M
3307B–USB–4/04
Hardware clears this bit after it receives an ACK. If the interrupt is enabled and if the TX Com-
plete bit is set, clearing the TX Packet Ready bit by the hardware causes an interrupt to the
microcontroller.
Bit 3 – STALL_SENT_ACK: Acknowledge Stall Sent Interrupt
Firmware sets this bit to clear STALL SENT, CSR bit 3. The 1 written in the CSRACK3 bit is
not actually stored and thus does not have to be cleared.
Bit 2 – RX_SETUP_ACK: Acknowledge RX SETUP Interrupt
Firmware sets this bit to clear RX SETUP, CSR bit2. The 1 written in the CSRACK2 bit is not
actually stored and thus does not have to be cleared.
Bit 1 – RX_OUT_PACKET_ACK: Acknowledge RX OUT PACKET Interrupt
Firmware sets this bit to clear RX OUT PACKET, CSR bit1. The 1 written in the CSRACK1 bit
is not actually stored and thus does not have to be cleared.
Bit 0 – TX_COMPLETE_ACK: Acknowledge TX COMPLETE Interrupt
Firmware sets this bit to clear TX COMPLETE, CSR bit0. The 1 written in the CSRACK0 bit is
not actually stored and thus does not have to be cleared.
Function End-point 0..3 Service Routine Register – FCSR0..3
Bit 7..4 – Reserved
These bits are reserved in the AT43USB353M 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[End-point] 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 Acknowl-
edge Register.
Bit 2 – Reserved
This bit is reserved in the AT43USB353M 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 over-
write 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 end-point.
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 end-point hardware to signal to the microcontroller that the IN transac-
tion 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.
