PDIUSBD 12芯片能够实现微控制器的并行总线到总线的接口功能，使用芯片可以实现多种类型的外设。
PDIUSBD12 may be used for implementing the interface between the parallel bus of the micro-controller and USB. With PDIUSBD12, users can implement multiple classes of USB functions.
也即当采用并行端口的众多多功能外设器件彼此相连时，在通用串行总线(usb)上可以实现他们的高速数据交换。
While many MFP devices still use the parallel port, there is a shift to Universal Serial Bus (USB) for the high-speed connection of peripheral devices.
