I am maintaining the software of a 68070 based board which uses the processors internal I2C controller to communicate to up to 16 slave processors. This I2C bus locks up under specific conditions.
The 68070 built in I2C controller is configured as the I2C master polling the 16 slaves for data.
The problem I have is that the 68070 data book is *very* skimpy with regard to the I2C controller register definitions.
Have googled for information but as this part is obsolete I have come up against a brick wall.
Has anybody written low level software for this part or has data sheets / applications notes for it that may have since dissapeared from the phillips site. I have the general I2C specification etc. but need specifics for the 68070.
Thanks in advance
