SINGLE-CHIP 8-BIT CMOS MICROCOMPUTER
MITSUBISHI MICROCOMPUTERS
[USB Endpoint 0 IN Control Register ] IN_CSR
This register contains the control and status information of the
endpoint 0. This USB FCU sets the OUT_PKT_RDY flag to
“
1
”
upon having received a data packet in the OUT FIFO. When read-
ing its one data packet from the OUT FIFO, be sure to set this flag
to
“
0
”
.
After a SETUP token is received, the MCU is in the
“
decode wait
state
”
until the OUT_PKT_RDY flag is cleared. If the
OUT_PKT_RDY flag is not cleared (indicating that the host re-
quest has not been successfully decoded), the USB FCU keep
returning a NAK to the host for all IN/OUT tokens.
Set the IN_PKT_RDY bit to
“
1
”
after the data packet has been
written to the IN FIFO. If this bit is set to
“
1
”
even though nothing
has been written to the IN FIFO, a
“
0
”
length data (NULL packet)
is sent to the host. The SEND_STALL bit is for sending a STALL to
the host if an unsupported request is received by the USB FCU.
This bit must be set to
“
1
”
. When the OUT_PKT_RDY flag is set to
“
0
”
for request reception, the USB FCU transmits a STALL signal
to the Host CPU. Perform the following three processes simulta-
neously:
Set SEND_STALL bit to
“
1
”
Set DATA_END bit to
“
1
”
Set OUT_PKT_RDY flag to
“
0
”
by setting SERVICED_OUT
_PKT_RDY bit to
“
1
”
.
Note that if
“
0
”
is written to the SEND_STALL bit before the
CLEAR_FEATURE (endpoint STALL) request has been received,
the next STALL will not be generated.
The DATA_END bit informs the USB FCU of the completion of the
process indicated in the SETUP packet. Set this bit to
“
1
”
when
the process requested in the SETUP packet is completed. (Con-
trol Read Transfer: set this bit after writing all of the requested
data to the FIFO; Control Write Transfer: set this bit to
“
1
”
after
reading all of the requested data from the FIFO.) When this bit is
“
1
”
, the host request is ignored and a STALL is returned. After the
status phase process is completed, the USB FCU automatically
clears it to
“
0
”
.

1: Control transfer ends before the specific length of data is
transferred during the data phase.
