combined externally, read the INT register to confirm which flag is asserted and write
“1” into the relevant bit.

SETUP-Stage has finished. Since UDC2 does not allow writing data into the
Endpoint0-FIFO before this command is issued, it will keep returning "NAK" to the
IN-Token from the host until the command is issued.
byte size of the data to send is larger than the MaxPacketSize, divide them into groups
of MaxPacketSize before writing. When the number of data reached the
MaxPacketSize, the EP0_DATASET flag is asserted.
UDC2 deasserts the EP0_DATASET flag and asserts INT_EP0. Any data remaining to
be transmitted should be written into the Endpoint0-FIFO.

command, UDC2 recognizes the end of the packet and transmits the short packet data.

Handshake for the STATUS-Stage. When the STATUS-Stage finished with no problem,
the INT_STATUS flag is asserted. When received a packet of STATUS-Stage from the
host before the “Setup_Fin” command is issued, UDC2 will return “NAK” and asserts
the INT_STATUS_NAK flag. Therefore, if this flag is asserted, be sure to issue the
“Setup_Fin” command.
