DCP is selected as a pipe, the buffer memory on the SIE side is also cleared. In this
case, confirming that FRDY = 1 is not necessary.
FRDY = 1 before checking the DTLN bit.

Description
Buffer Memory Valid Flag
Writing 1 to this bit is valid when the direction of data
packet is the transmitting direction (when data is
being written to the buffer memory). When the
direction is set to the receiving direction, this bit
should be cleared to 0.
0: Invalid
1: Writing ended
CPU Buffer Clear*
This bit should be used to clear the buffer with this bit
with the pipe invalid state by the pipe configuration
(PID = NAK).
0: Invalid
1: Clears the buffer memory on the CPU side.
FIFO Port Ready
Confirming the FIFO port state by reading this bit
requires an access cycle of at least 450 ns after the
pipe has been selected.
0: FIFO port access is disabled.
1: FIFO port access is enabled.
Reserved
This bit is always read as 0. The write value should
always be 0.
Receive Data Length*
The length of the receive data can be confirmed.
