6.2.1. Changing the Stack Area

For the stack area to be used in the 740 family, select page 0 (00h–FFh) or page 1 (100h–

1FFh).

The ICC740 uses this stack area as CSTACK segment.

With standard settings of the M3T-ICC740, the addresses 100h–13Fh in page 1 are used for

the stack area.

-Z(NAPGE)CSTACK+40=100

The following shows a few examples of how to change.

Example 1: To use the addresses 120h–14Fh in page 1 for the stack area, alter the file as

shown below.

-Z(NAPGE)CSTACK+30=120

Example 2: To change the stack area to page 0, alter the file as shown below.

-Z(ZPAGE)CSTACK+40

Page 0 contains the segments that must be located in the SFR area and in page

The above statement directs that 40h bytes of area following the

INT_EXPR_STACK segment written in the line 54 be used.
