The EP2 buffer also supports DMA operation. The MCU needs to initialize the DMA operation through the

Set DMA command. Once DMA operation is enabled, data will be moving between the system memory

and FT120 endpoint buffer under the DMA controller. Buffer switching between ping buffer and pong

buffer is handled automatically.
