C166: FUNCTIONAL PROBLEM CPU.12

Information in this article applies to:

• C166 Version 3.12
• C166 Version 4.05
• µVision Version 2.05

QUESTION

We are using the ST10F167. The C initialization code I have uses EXTS. I believe that it is not initializing my variables correctly because of functional problem CPU.12. Do you have C initialization code that works around this problem?

ANSWER

Modify the START167.A66 and move the following section...

;------------------------------------------------------------------------------
;
; The following code is necessary to set RAM variables to 0 at start-up
; (RESET) of the C application program.
;

$IF (CLR_MEMORY = 1)

to the end of the file with the corresponding section from the STARTUP.A66 file. STARTUP.A66 does not use the EXTS sequences but performs the same function as START167.A66.
