Preliminary
Description
Software should not rely on the value of a reserved bit. To provide
compatibility with future products, the value of a reserved bit should be
preserved across a read-modify-write operation.
Flush FIFO
The CPU writes a 1 to this bit to flush the next packet to be
transmitted/read from the endpoint 0 FIFO. The FIFO pointer is reset
and the TXRDY/RXRDY bit is cleared.
Important:
FLUSH should only be used when TXRDY/RXRDY is set.
At other times, it may cause data to be corrupted.
