读I2C组件的数据表如何从从属的子地址读取

大家好，
我正在使用UDB I2C主组件与PSoC 5LP CY8CKIT-059一起工作。我没有问题写I2C设备，我想与使用Uti8I2C*MaultRead Bufff通信，但在读完I2C组件的数据表之后，我无法理解如何从从属的子地址读取。
i2c_masterreadbuf的卡片（卡片slaveaddress，uint8 * rddata，uint8 CNT，uint8模式）似乎是功能我会用，但我可以从文件告诉，这只会读“碳纳米管”的字节从I2C Slave的基地址数。我能从子地址读吗？再次，我已经阅读数据表和我没有办法得到答案的形式。
谢谢！

                                            Hello all,

I am working with the PSoC 5LP Cy8CKIT-059 using a UDB I2C master component. I have no trouble writing to the I2C device I want to communicate with using uint8 I2C_MasterReadBuf, but after reading through the datasheet for the I2C component, I cannot figure out how to read from a sub-address of the slave.

The uint8 I2C_MasterReadBuf(uint8 slaveAddress, uint8 * rdData, uint8 cnt, uint8 mode) seems to be the function I would use, but as far as I can tell from the documentation, this will only read "cnt" number of bytes starting from the I2C slave's base address. Is it possible for me to read from a sub-address? Again, I have read the datasheet and I have no been able to get an answer form that.

Thanks!
