Configuration

The selected configuration can be configured by SPI, there are 2 bits dedicated to

configuration selection:

The configuration is enabled only when EN pin is logic 0.

In configuration 4, the output DRN/SRC1-4 can be controlled by SPI only; for those outputs

the selection between high side and low side configuration can be done through the

dedicated bit (bit8 of Device general configuration register).
