NAK
x
NAK = 0
No valid data in buffer. Ready for host-out
NAK = 1
Buffer contains a valid packet from host (host-out request is NAK).

STALL
0
USB stall condition indication. Set by UBM, but can be set/cleared by the MCU.
STALL = 0
No stall
STALL = 1
USB stall condition. If set by the MCU, a STALL handshake is initiated and the bit is cleared
automatically.

DBUF
x
Double buffer enable
DBUF = 0
Primary buffer only (X-buffer only)
DBUF = 1
Toggle bit selects buffer
5
TOGLE
x
USB toggle bit. This bit reflects the toggle sequence bit of DATA0, DATA1.
