USB with MCU Interface
There are eight registers, including Pipe_ctrl, Address+Remote_WakeUp, STALL, SIES, MISC, Endpt_EN and
FIFO0~FIFO3 in this buffer function.

Register Memory Mapping
Address+Remote_WakeUp register represents current address and remote wake-up function. The initial value is
00000000 from MSB to LSB.

Address+Remote_WakeUp Register
STALL, Pipe_ctrl and Endpt_EN Registers
PIPE register represents whether the endpoint corresponding is accessed by host or not. After ACT_EN signal being
sent out, MCU can check which endpoint had been accessed. This register is set only after the time when host access
the corresponding endpoint.
STALLregister shows whether the endpoint corresponding works or not. As soon as the endpoint work improperly, the
bit corresponding must be set.
Pipe_ctrl register is used for configuring IN (Bit=1) or OUT (Bit=0) pipe. The default is define IN pipe. Where Bit0
(DATA0) of the Pipe_ctrl register is used to setting the data toggle of any endpoint (except endpoint 0) using data tog-
gles to the value DATA0. Once the user want the any endpoint (except endpoint 0) using data toggles to the value
DATA0, the user can output a LOW pulse to this bit. The LOW pulse period must at least 10 instruction cycle.
Endpt_EN register is used to enable or disable the corresponding endpoint (except endpoint 0). Enable Endpoint
(Bit=1) or disable Endpoint (Bit=0).
