AT43USB325
The microcontroller should write into the FIFO only if this bit is cleared. After it has completed
writing the data, it should set this bit. This data can be of zero length.
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.
