Modify the value of variable in assembly

[girichavana]

Hello Support,

I am working on HCS08, with CW 10.1 assembly language programming.

I need support to write a assembly routine to modify the value of 32 bit variable.

Please support in this.

Regards

Giri

Hi Giri,

I believe this is the same issue as service request 1-1314984694

CW for 8bit mcu assembly instruction doesn’t have a simple instruction that can modify the value of a 32bit variable. This is limited by the related register width.

See below code: it is to set 32bit variable temp_long as 0xaabbccdd

temp_long ds 4

… …

       ldhx  #$aabb

       sthx  temp_long

       ldhx  #$ccdd

       sthx temp_long+2

Hope this helps!
