How do we add 90 to 8C technically
The instruction in your question is a move.w, which does replacement, not addition. The w stands for word, which on the 68k is 16 bits. Using a word sized operation, it is loading an immediate value into a register.
What is the D0?
d0.w gets replaced with 0x008c,
which means that d0.l is then 0x025C008c.
and the CCR?
Condition codes:
X N Z V C
- * * 0 0
So, N & Z are set by the value of the word that was moved, which was 0x008c; while V & C are cleared, and X is unmodified.
