TPS65910的I2C问题

TPS65910具有两个I2C接口，数据手册是这样说的：TPS65910 has two slave I2C interfaces: one is a general-purpose interface to control the internal configuration registers, the second is dedicated to SmartReflex applications such as dynamic voltage frequency scaling (DVFS) or adaptive voltage scaling (AVS).

我想问的是，当我使用TPS65910AA1专门驱动AM3359时候，里面不是固化EEPROM了吗？还需要外接I2C来进行register的配置吗？另外，我看开发板中SCL_SCK和SDA_SDI是接到AM3359上的，而另外一组I2C SCLSR_EN1和SDASR_EN2是没有接到AM3359上的。
