When data receive ended, the buffer
is set to Ready state (read enable)
and occurs INTR interrupt
Continuous receiving is available
before data read.
In OUT token receive to this
endpoint, M66290A occurs
INTN interrupt and do NAK
handshake.
It becomes receive enable
after read of data1 ended.
And occurs INTR interrupt
because the buffer is ready.

(1) Receiving
Below are the receive status examples
of the endpoint which is set to double buffer.
Endpoint buffer status
Figure 7. Double buffer activities-1
Double buffer operations
The endpoint FIFO of EP1 to EP5 can be
set to double buffer constitution.
So a double of transfer data of its buffer size, which
is set, can be stored.
