I am very new to this MCU .Please let me know what to change in this code for implementing uart bootloader for s12ZVH.
I recommend you to follow the application note AN12086 Simple Serial Bootloader for S12Z - AN draft
There you can find the detailed description.
I know you already saw it because of your previous thread, but I'm afraid you will not find better documentation with software for S12Z devices.
