USB with MCU Interface
There are eight registers, including Pipe_ctrl, Address+Remote_WakeUp, STALL, SIES, MISC, Endpt_EN and FIFO
0~FIFO 2 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.

Remote Wake-up Function
0: Not this function
1: The function exists
Address+Remote_WakeUp Register
STALL, Pipe_ctrl and Endpt_EN Registers
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).
The bitmaps are list as follows:
