endpoint 0 FIFO. The value returned changes as the contents of the FIFO change and is only valid
while the RXRDY bit is set.

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.
FIFO Count

bytes in the endpoint 0 FIFO.
