OCSTSTAL : Out Control 1 Sent Stall bit.
USB sets this bit when OUT token is terminated due to a
STALL handshake,.
When data packet in an OUT token is bigger than MAXP data,
USB generates a stall handshake to host.
MCU clears this bit by writing a ‘0’.
OCSDSTAL : Out Control 1 Send Stall bit.
MCU sets this bit to ‘1’ and a STALL handshake is generated
to USB. To terminate the STALL status, MCU writes ‘0’ to
this bit.

Clear OCFFLU : Out Control 1 FIFO Flush bit.
MCU sets this bit to ‘1’ to flush FIFO and clears this bit to stop
the flush operation. This bit can be set if OCOPR bit is set.
Data packet fetched by MCU will be flushed.
R/W OCERR : Out Control 1 Data Error bit
An error (bit stuffing or CRC) in the data packet fetched by
MCU from FIFO will cause this bit to be set. This bit is
automatically cleared when OCOPR bit is cleared.
