I2C Specification

I’ve encountered problems using the I2C bus. I’ve added an LM75 temp sensor and 5 additional LM73 temp sensors off board. I haven’t found the version of I2C implemented on the RCM3000/BL2600 combination. Standard or Fast? The problems I’m encountering seem to be related to data setup and hold times. Is this I2C port a true I2C device or a wanna be?
