Beware!

AN554 and AN578 are only approximations to I2C.

At the bit level, the I2C spec says that an I2C slave
holds SCL low to 'wait-state' the master.

Looking closely at AN578, you see that the code
interprets this as a bus error.

This is a serious and fundamental bug IMHO.

I'm horrified at the number of people looking for
example I2C code, who then get pointed to these notes.

They really are appalling.

I'm writing PIC code which uses the I2C bus,
and I think I would have been better off writing
I2C code from scratch from the I2C bus spec
than starting off with these notes.
