12Ah-12Bh D_EnEP_OUT_H,L
This sets the endpoint to be enabled as OUT when in device mode.
The response shown below is returned and the corresponding bit is set to "1" if a transaction is issued (OUT
token received) from the host to the endpoints enabled by D_EnEP_OUT_H,L, except those appropriately set in
the D_EPx{x=0,a-e} registers and for which joining is set by the AREAn{n=0-5}Join.JoinEPxCHx{x=0,a-e} bit.
The response returned to the OUT token depends on the D_EnEP_OUT_ISO_H,L setting. The data transmitted
by the host is not accepted, and no handshake is returned for an endpoint for which the corresponding bit is set to
"1"; a NAK is returned to the host for an endpoint cleared to "0." A NAK is returned if the device is set to HS
and a PING token is issued by the host.
If the corresponding bit in this register is set, enable transactions by appropriately setting the D_EPx{x=0,a-e}
related registers and joining the endpoint to the FIFO area using the AREAn{n=0-5}Join.JoinEPxCHx{x=0,a-e}
bit.
