USB with MCU Interface
There are eight registers, including Pipe_ctrl, Address+Remote_WakeUp, STALL, PIPE, SIES, MISC, FIFO 0 and
FIFO 1 in this buffer function.
Address+Remote_WakeUp register represents current address and remote wake-up function. The initial value is
The Pipe_ctrl, STALL and PIPE are bitmap ones. The Pipe_ctrl Register is used for configuring IN (Bit=1) or OUT
(Bit=0) Pipe and only for HT82M99AE body. The default is defined as IN Pipe. The PIPE register represents whether
the corresponding endpoint is accessed by host or not. After a USB interrupt signal is being sent out, the MCU can
check which endpoint had been accessed. This register is set only after the host accessed the corresponding endpoint.
The STALL register shows whether the corresponding endpoint works or not. As soon as the endpoint works improp-
erly, the corresponding bit must be set. The bitmaps are listed as follows:
