QUESTION

I need the header file Dallas 89C420. The header file on my µVision CD and on your web site appears to be for a 80C420 device because it contains this comment:

REG420.H
Header file for Dallas 80C420.
Copyright (c) 1988-2002 Keil Elektronik GmbH and Keil Software, Inc.
All rights reserved.

Where can I get the header file for the Dallas 89C420?

ANSWER

The REG420.H file on your µVision CD and on the web site are both the correct header file for the Dallas 89C420. The 80C420 in this line is incorrect. It should read 89C420. This will be corrected in the next release.

Dallas Semiconductor does not make an 80C420 microcontroller.
