Is TWI compatible with the SMBus?

Hi,

 

I am using a BF547M processor and having issues communicating with a SMBus

device using the TWI interface on the DSP.  The SMBus specifies a data hold time

of 300nsec.  The I2C specifies a data hold time of 0.  My tests show that my

current setup has a data hold time of about 150nsec.

 

Is there some sort of work around or register setting that I am missing

on the BF547M that can increase this data hold time to make the TWI

compatible with the SMBus?

 

Thanks,

Joe
