Appendix C - Software Identification of the
Revision 12-05-06
In order to properly write software to work with the COM20020 Rev B, C and D it is necessary to be able to
identify the different revisions of the part.
To identify the COM20020 Revision follow the following procedure:
1.
2.
3.
* If the value read from Register-6 is 0x98 then the part is a COM20020 Rev B or earlier
* If the value read from Register-6 is 0x9A then go to next step below
4.
5.
* If the value read from Register-5 is 0x00 then the part is a COM20020 Rev C
* If the value read from Register-5 is 0x80 then the part is a COM20020 Rev D
Write 0x98 to Register-6 (Address = 6)
Write 0x02 to Register-5 (Address = 5)
Read Register-6
Write 0x80 to Register-5
Read Register-5
COM20020 Rev B, Rev C and Rev D
