TPS65987DDK: Which I2C to use when configuring

Part Number: TPS65987DDK

Hello team,

I would like to configure TPS65987DDK from external controller, not EEPROM.

There are I2C1, and I2C2, which one should I use to configure register setting for TPS65987DDK?

(It says I2C to system control, so I assume I2C1, is this correct?)

Also can I leave the unused I2C/SPI pins floating?

Best Regards,
Kei Kuwahara
