MOVH : MOVe Halfword High

Like MOV, this instruction copies either

to the destination register. However, this data is shifted left by 16 bits and the lower half-word is filled with Zeroes (like SHL would do). This instruction is created to make 32-bits data in YASEP32 with code sequences such as:

; put 12345678h in R1
 MOVH 1234h R1 ; MSB
 OR   5678h R1 ; LSB
