Value
R/W Description
4 EP2 PKTE Undefined W EP2 Packet Enable
After one packet of data has been written to the
endpoint 2 transmit FIFO buffer, the transmit data is
fixed by writing 1 to this bit.
3  Undefined  Reserved
The initial value should not be changed.
2 EP0s RDFN Undefined W EP0s Read Complete
Write 1 to this bit after data for the EP0s command
FIFO has been read. Writing 1 to this bit enables
transfer of data in the following data stage. A NAK
handshake is returned in response to transfer
requests from the host in the data stage until 1 is
written to this bit.
1 EP0o RDFN Undefined W EP0o Read Complete
Writing 1 to this bit after one packet of data has been
read from the endpoint 0 transmit FIFO buffer
initializes the FIFO buffer, enabling the next packet to
be received.
0 EP0i PKTE Undefined W EP0i Packet Enable
After one packet of data has been written to the
endpoint 0 transmit FIFO buffer, the transmit data is
fixed by writing 1 to this bit.
