4.3.4 SPI Write

The I3C Controller wants to write data to an SPI client device.

The I3C Controller sends a Private Write transaction with Function ID, and data to write to the client device in its data word. The PIC MCU decodes the Function ID, selects the SPI client device (sets CS pin low) based on the Client ID and initiates SPI Write with the data. Once the write is completed, the SPI client is deselected (sets CS pin high).
