MOV : MOVe

This instruction copies either

• a register's content (si4) (short register form or extended or extended register form)
• a 4-bits immediate value in si4 (short immediate)
• a 6-bits immediate value (extended immediate form)
• a 16-bits immediate value (long immediate form with YASEP16)
• a 20-bits immediate value (long immediate form with YASEP32)

to the destination register (snd for RR and iR, or dst for the others).

When the size of the immediate data is smaller than the register, that data is sign-extended. If a 32-bit wide constant needs to be loaded, use MOVH to overwrite the MSB.
