SCI Activated Bootloader

I have downloaded many examples of a bootloader for the S12x and all of them require a pin to be held low to activate the bootloader. I want to be able to send a command via SCI to the application code to make it jump to the bootloader. In the past with the Atmel the application was sent a command via SCI that then set BootLoad = TRUE ,and this code then jumped to the bootloader.


If (BootLoad == TRUE)   {    // Got command to jump to bootloader

    asm("jmp 0x3F800");



Is there a bootloader example that can work this way. Or how do I modify the existing examples so they do not look for a pin change.
