W
CLEAR
The MCU should write a "1" to this bit to
clear SETUP_END
W
CLEAR
The MCU should write a "1" to this bit to
clear OUT_PKT_RDY
R/W
CLEAR
The MCU should writes a "1" to this bit at
the same time it clears OUT_PKT_RDY, if
it decodes an invalid token.
0 = Finish the STALL condition
1 = The USB issues a STALL and shake
to the current control transfer.
R
SET
The USB sets this bit when a control
transfer ends before DATA_END is set.
When the USB sets this bit, an interrupt
is generated to the MCU.
When such a condition occurs, the USB
flushes the FIFO and invalidates MCU
access to the FIFO.
SET
CLEAR
The MCU sets this bit below conditions:
1. After loading the last packet of data
into the FIFO, at the same time
IN_PKT_RDY is set.
2. While it clears OUT_PKT_RDY after
unloading the last packet of data.
3. For a zero length data phase.
CLEAR
SET
The USB sets this bit if a control
transaction is stopped due to a protocol
violation. An interrupt is generated when
this bit is set. The MCU should write "0"
to clear this bit.
SET
CLEAR
The MCU sets this bit after writing a
packet of data into EP0 FIFO. The USB
clears this bit once the packet has been
successfully sent to the host. An interrupt
is generated when the USB clears this bit,
so as the MCU to load the next packet.
For a zero length data phase, the MCU
sets DATA_END at the same time.
R
SET
The USB sets this bit once a valid token
is written to the FIFO. An interrupt is
generated when the USB sets this bit. The
MCU clears this bit by writing a "1" to the
SERVICED_OUT_PKT_RDY bit.
