This procedure using the USB chip MSP430F149 control PDIUSBD12 USB chip with the MCU data ports according to the P5 port to connect one-to-one relationship, while the control port and the MCU to connect the IO relations: P2.0 WR_N, P2.1 RD_N, P2. 2 A0, P2.3 CS_N. MSP430 MCU because there is no external bus interface, so it is necessary to the above four IO and P5 mouth with simulation data/address multiplexed bus to read and write timing in order to achieve the operation of the D12.
