SPI connection

To communicate with the device using the STEVAL-IPE023V1 isolated USB dongle, the

STPM3x SPI peripheral has to be selected. All SWC1 switches have to be turned in OFF

position before the device powers up. SPI pins are available in J6 connector (see Table 4)

for 10-pin flat cable interfacing either to the STEVAL-IPE023V1 or to an external MCU.

Note:

The STEVAL-IPE023V1 provides isolation, while J6 pins are not isolated.
