I did not follow the thread yet, sorry. I implemented AN2819 for Linux (see http://lxr.linux.no/#linux+v2.6.31/drivers/i2c/busses/i2c-mpc.c) some time ago using Timur's table approach. But there is no difference between the table and the algorithm to calculate the value. The table is actually derived from the same algorithm.
The problem with the table is that it does not allow for flexibility in choosing dfsr. When I implemented the table code, I did not think that this was a problem, but apparently it is.
What would be the criteria to choose dfsr, especially for a defined bus frequency.
