Question

In Assembly 68k, write the following code.

Assume the student number is 123456.

1- Reserve locations at $400 to hold the name of our institution
and call it NAME
2- Write a code segment called CODE at address $800 to
replace the 32-bit signed integer in D0 with its absolute value
3- Compare A0 with student number, and transfer control to
address $96000 if it is less or same, else stop fetching
4- Start a new code section at address $96000
5- Invert the least significant byte of DO
6- Save full length D0, D4, A1 to A5 to address $124680
7- Disable all priority interrupts lower than level 4
8- Load the stack pointer with $98700
9- Place the least significant two bytes of your student number
in the upper half and the rest in the lower half of DO
10- Clear the byte in memory at address FLAG if DO = 0, else
make it all ones
%3D
