Note 1. The SPI port of the host MCU must be set up as follows:

1. SPI master mode.

2. SCK idle state = low

3. Clock edge for MOSI data shift = high to low

4. Clock edge for input data (MISO) sample by the Processor = low to high (or bit middle)

Note 2. To conform with the multibyte transmission protocol of LS7366R, the SS/ output port

of the MCU may require direct manipulation by the application program.
