2.Process of using general SPI Master device

1. Configure Input/Output direction on SPI Master Device pins.

2. Configure nSCS as ‘High’ on inactive

3. Write target address for transmission on SPDR register (SPI Data Register).

4. Write OP code and data length for transmission on SPDR register.

5. Write desired data for transmission on SPDR register.

6. Configure nSCS as ‘Low’ (data transfer start)

7. Wait for reception complete

8. If all data transmission ends, configure nSCS as ‘High’
