8.3.8.8.3 Connection Example

When more than 1 MCP3910 device is connected to SPI, the SDO data lines from the MCP3910 products must be multiplexed prior to driving the SPI MOSI line.

MOSI multiplexing must be performed by successively enabling each SDO line from the MCP3910 with external discrete components. See the following figure.

In this mode, the NPCS lines are activated successively after each frame reception.

The polarity of chip select output NPCS is defined by configuring the Chip Select Inversion Enable (CSIE) bit in FLEX_SPI_MR.
