LMP91300的通讯问题

数据手册写的比较含糊，到底LMP91300的通信硬件该怎么连接呢？

借助电源的巧妙通信接口

Single-Wire Interface (SWIF)

The LMP91300 uses a bi-directional Single Wire Interface protocol to program and read registers. To communicate with the LMP91300 (slave) through the SWIF interface, the micro controller (master) must transmit (write) data through the DC loop supply voltage that should be set to +8V during programming or communication. This superimposed signal of pulses transitions between 8V and 12V is on top of the +8V DC loop supply voltage.
