Application notes 21, 22 - where?

Is there any more detail to these - I found the code - it talks about:

; Program Description:
; This program demonstrates the ability of the SX28 to interface directly
; to the ISA-XT bus while simultaneously implementing a single-channel I2C
; multi-master.
; Additional documentation:
; i. ISA-SX Application Note #22
; ii. ISA-I2C Application Note #21

Is there more documentation for these application notes?

Thanks!

    Look Here and Here

    If not the code is very well documented

    Great links - thanks!
    I didn't see anything ISA / AN 21/22 related there - I can figure it out from the code, just figured maybe I was missing the rest of the docs.

    Phillips owns I2C, so the code you are looking for may have been removed due to being unlicensed. Early on, the SXes did successful work with replicating CANbus as well and you have to get a license to use it. That code was removed. And I am not sure about the ISA legalities of who owns what. You don't get very popular with these people when your chip can replicate what they want to control.
