Looks like an assembly language program for a Motorola 68HC11 class controller. And you
would for sure be on the wrong forum to ask questions about this animal...;o}

If you need help on assembler for this particular target, try here http://www.owlnet.rice.edu/~elec201/Book/6811_asm.html

Or try contacting the original author of the code fragment you have.
