The value read from this bit is always 0. Do not set this bit.
Endpoint 6 FIFO Reset
Set this bit and reset the endpoint FIFO prior to any other operation, upon
hardware reset or when an USB bus reset has been received.
Then, clear this bit to complete the reset operation and start using the FIFO.
Endpoint 5 FIFO Reset
Set this bit and reset the endpoint FIFO prior to any other operation, upon
hardware reset or when an USB bus reset has been received.
Then, clear this bit to complete the reset operation and start using the FIFO.
Endpoint 4 FIFO Reset
Set this bit and reset the endpoint FIFO prior to any other operation, upon
hardware reset or when an USB bus reset has been received.
Then, clear this bit to complete the reset operation and start using the FIFO.
Endpoint 3 FIFO Reset
Set this bit and reset the endpoint FIFO prior to any other operation, upon
hardware reset or when an USB bus reset has been received.
Then, clear this bit to complete the reset operation and start using the FIFO.
Endpoint 2 FIFO Reset
Set this bit and reset the endpoint FIFO prior to any other operation, upon
hardware reset or when an USB bus reset has been received.
Then, clear this bit to complete the reset operation and start using the FIFO.
