MISC register combines a command and status to control desired endpoint FIFO action and to show the status of the
desired endpoint FIFO. The MISC will be cleared by USB reset signal.
Bit No.
Label
R/W
Function
0
REQ
R/W
After setting the other status of the desired one in the MISC, endpoint FIFO can be
requested by setting this bit to 1 . After the job has been done, this bit has to be
cleared to 0 .
1
TX
R/W
This bit defines the direction of data transferring between MCU and endpoint FIFO.
When the TX is set to 1 , this means that the MCU wants to write data to the end-
point FIFO. After the job has been done, this bit has to be cleared to 0 before termi-
nating request to represent the end of transferring. For reading action, this bit has to
be cleared to 0 to represent that MCU wants to read data from the endpoint FIFO
and has to be set to 1 after the job is done.
2
CLEAR
R/W
Clear the requested endpoint FIFO, even if the endpoint FIFO is not ready.

SELP1
SELP0
R/W
Defines which endpoint FIFO is selected, SELP1,SELP0:
00: endpoint FIFO0
01: endpoint FIFO1
10: endpoint FIFO2
11: reserved
5
SCMD
R/W
Used to show that the data in endpoint FIFO is a SETUP command. This bit has to
beclearedbyfirmware.Thatistosay,eventheMCUisbusy,thedevicewillnotmiss
any SETUP commands from the host.
6
READY
R
Read only status bit, this bit is used to indicate that the desired endpoint FIFO is
ready to work.
7
LEN0
R/W
Used to indicate that a 0-sized packet is sent from a host to the MCU. This bit should
be cleared by firmware.
MISC (46H) Register
The MCU can communicate with the endpoint FIFO by setting the corresponding registers, of which address is listed in
the following table. After reading the current data, next data will show after 2 s, used to check the endpoint FIFO status
and response to MISC register, if read/write action is still going on.

There are some timing constrains and usages illustrated here. By setting the MISC register, MCU can perform reading,
writing and clearing actions. There are some examples shown in the following table for endpoint FIFO reading, writing
and clearing.
